Edible Ginkgo biloba: Ginkgo biloba is healthy and long-lived. Ginkgo biloba was listed as a royal tribute in the Song Dynasty. Japanese people have the habit of eating ginkgo every day. Westerners must eat ginkgo at Christmas. As far as eating methods are concerned, Ginkgo biloba mainly includes fried food, baked food, cooked food, side dishes, cakes, candied fruit, canned food, beverages and alcohol. However, improper dosage and eating method of Ginkgo biloba can cause poisoning. In order to prevent ginkgo poisoning, cooked food and eating less are the fundamental methods. Raw food (with shell and coating) 5-7 capsules for adults and 2-5 capsules for children according to their age and weight, which can be taken again after 4 hours. Raw food must be shelled, red and soft, and removed from the heart (germ). If it is cooked food, it is advisable to take 20~30 capsules each time, such as shelling, removing red soft film and removing embryo, even if the dose is large, poisoning will not occur. The taste is flat, sweet and bitter, and the toxicity is small; Lung and kidney meridians of human body. Efficacy is mainly used to astringe lung qi, relieve asthma and cough, relieve stranguria, reduce defecation, disinfect and kill insects. Indications: Asthma, phlegm cough, wet dream, leucorrhea, turbid urine, infantile diarrhea, insect accumulation, intestinal wind and visceral toxicity, gonorrhea, frequent urination, scabies, lacquered sores and leukoplakia. Every 100g nutrient contains protein 6.4g, fat 2.4g, carbohydrate 36g, crude fiber 1.2g, sucrose 52g, reducing sugar 1. 1, calcium 10mg and phosphorus 2 1 8mg. Medicinal use of Ginkgo biloba: The medicinal use of Ginkgo biloba is mainly reflected in medicine, pesticides and veterinary drugs. In the Ming Dynasty, Li Shizhen once said: "Entering the lung meridian can benefit the temper, stop asthma and cough, and reduce defecation." Ginkgo biloba in Ben Feng Jing Yuan written by Zhang Lulu in Qing Dynasty has the effects of resolving phlegm, detoxicating and killing insects, and can be used to treat "furuncle, ulceration of mammary abscess, dental caries, infantile diarrhea, leucorrhea with red and white discharge, chronic stranguria, nocturnal emission and enuresis". In the Ming Dynasty, Chinese patent medicines made of Ginkgo biloba appeared in Jiangsu, Sichuan and other places for clinical use. Therapeutic effect 1. Antibacterial and bactericidal Ginkgo biloba leaves contain ginkgolic acid and ginkgol, which have been proved by experiments to have antibacterial and bactericidal effects and can be used to treat respiratory tract infectious diseases. Ginkgo biloba extract can inhibit various fungi to varying degrees, and can relieve itching and treat tinea. 2. Eliminating illness and relieving cough Ginkgo biloba is sweet and bitter, and has the effect of astringing lung qi, relieving asthma and relieving cough. It has an auxiliary dietotherapy effect on cough caused by lung diseases, asthma with weak constitution in the elderly and asthma with various phlegm types. 3. Ginkgolic acid and ginkgol contained in the testa of Ginkgo biloba have anti-tuberculosis effects. Ginkgo biloba leaves soaked in oil have a strong inhibitory effect on mycobacterium tuberculosis, and fresh fruits soaked in raw vegetable oil have a certain effect on improving symptoms such as fever, night sweats, cough and hemoptysis, and loss of appetite caused by tuberculosis. Therefore, it can be used to treat pulmonary tuberculosis. 4. Stop turbidity and reduce stool. Modern medical research has found that the so-called Ginkgo biloba can contract the sphincter of bladder. It can be used for the adjuvant treatment of infantile enuresis, frequent micturition due to qi deficiency, excessive leucorrhea and unconsolidated nocturnal emission. 5. Lowering serum cholesterol and dilating coronary arteries Ginkgo biloba leaves contain shikimic acid, ginkgetin, isoflavones and sterols. In recent years, it has been used to treat hypertension, coronary heart disease, angina pectoris, cerebral vasospasm, hypercholesterolemia and other diseases. [Edit this paragraph] Ginkgo biloba is a positive tree, which likes deep loam with suitable moisture and good drainage, and is suitable for growing in subtropical monsoon region with superior hydrothermal conditions. It can grow well in acidic soil (pH4.5) and calcareous soil (pH8.0), and neutral or slightly acidic soil is the most suitable. It can endure drought in places that are intolerant of stagnant water, but it can't grow well in places that are too dry and rocky slopes or with low humidity. Ginkgo biloba has a long life, more than 3000 years old. Slow initial growth, long life and strong tillering ability. Female plants generally begin to bear fruit in about 20 years, and trees that have been 500 years old can still bear fruit normally. Generally, it germinates from late March to early April, blooms from early April to mid-April, and the seeds mature 10 from late September to early June, and shed leaves from late June to 10. Ginkgo biloba in the wild state is distributed in the subtropical monsoon region, with superior hydrothermal conditions. The annual average temperature 15℃, the extreme minimum temperature can reach-10.6℃, the annual precipitation 1500- 1800 mm, the soil is yellow soil or yellow brown soil, and the pH value is 5-6. Associated plants mainly include Cryptomeria fortunei, Dictyophora dictyophora, Torreya grandis, Cunninghamia lanceolata, Blue Fruit Tree, Liquidambar formosana, Litsea cubeba, Fragrant Fruit Tree, Populus davidiana and Phyllostachys pubescens. [Edit this paragraph] Ginkgo biloba is widely distributed in China, Japan, North Korea, South Korea, Canada, New Zealand, Australia, the United States, France, Russia and other countries and regions. Ginkgo biloba is widely distributed geographically. From the perspective of horizontal natural distribution, Ginkgo biloba near the 30o line in north latitude has the longest distance from east to west. With the increase or decrease of this latitude, the distance between east and west of Ginkgo biloba is gradually shortened. The higher the latitude, the more inclined the distribution of Ginkgo biloba to the eastern coast, and the lower the latitude, the more inclined the distribution of Ginkgo biloba to the plateau and mountainous areas in the southwest. Ginkgo biloba in China is mainly distributed in temperate and subtropical climate zones, with a marginal distribution of "Shenyang in Liaoning Province in the north, Guangzhou in Guangdong Province in the south, Nantou in Taiwan Province Province in the southeast, Changdu in Xizang Autonomous Region in the west and Putuo Island in Zhoushan, Zhejiang Province in the east", spanning 2LO301-41O4 in the north latitude and 97O-65438 in the east longitude. Ginkgo biloba resources in China are mainly distributed in more than 60 counties and cities in Shandong, Zhejiang, Anhui, Fujian, Jiangxi, Hebei, Henan, Hubei, Jiangsu, Hunan, Sichuan, Guizhou, Guangxi and Guangdong provinces. In terms of resource distribution, Shandong, Zhejiang, Jiangxi, Anhui, Guangxi, Hubei, Sichuan, Jiangsu, Guizhou and other provinces have the most resources, but the distribution of resources in various provinces is also uneven, mainly concentrated in some counties or cities, such as Xinyi, Dafeng, Pizhou and Wuxian in Jiangsu, Tancheng and Xincun in Shandong, Tai 'an and Yantai in Shandong, and Luoyang Town in Suizhou, Hubei. Many ginkgo experts believe that natural ancient ginkgo groups have been discovered in remote mountainous areas such as Tianmu Mountain in Zhejiang, Dahongshan Mountain in Hubei and Shennongjia. They are extremely precious cultural heritage and natural landscape, and play an important role in improving the surrounding ecological environment, studying biodiversity and ensuring the sustainable utilization of ginkgo genetic resources. Natural resource researchers also found that Ginkgo biloba is accompanied by Metasequoia glyptostroboides, Davidia involucrata and other relict plant in the deep mountain valleys of Hubei and Sichuan. The vertical distribution of Ginkgo biloba is also due to the different latitudes and landforms in the region, and the distribution altitude is not exactly the same. Generally speaking, the vertical distribution span of Ginkgo biloba is large, and the well-grown ancient Ginkgo biloba trees are distributed in the eastern plain from several meters to tens of meters above sea level to the southwest mountainous area at an altitude of about 3000 meters, such as Taixing in Jiangsu, 300 meters above sea level in Wuxian, 40 meters above sea level in Tancheng, Shandong, 1600 meters above sea level in Dujiangyan, Sichuan and 1500 meters above sea level in Gansu. Yunnan is 2000 meters away, but these distribution conditions do not mean that Ginkgo biloba can be distributed in all areas within such a vertical span, because besides latitude and altitude, topography and soil are also very important factors, such as soil water content, salt content, sunshine and extreme temperature, which directly limit the development of Ginkgo biloba. In the marginal areas of natural distribution of Ginkgo biloba, there may be a microclimate conducive to the growth of Ginkgo biloba due to terrain and other factors, and Ginkgo biloba can still grow well. Similarly, in the natural distribution area of Ginkgo biloba, due to the differences of microclimate or topography, soil and hydrothermal conditions, there are also areas that are not suitable for the growth of Ginkgo biloba, so in the natural distribution area, Ginkgo biloba is mostly distributed in points. From the climatic factors, the vertical distribution is mainly concentrated in the annual average temperature of 8O -20o, and the absolute minimum temperature is not lower than -20o, which is in line with the ecological habits of Ginkgo biloba. [Edit this paragraph] Protection value Ginkgo biloba is the only kind of ginkgo biloba, a famous living fossil plant, and a precious wood and dried fruit tree species. Because of its many primitive characters, it is of great value to study the phylogeny of gymnosperms, paleoflora, paleogeography and Quaternary glacial climate. The leaves are peculiar and quaint, and they are beautiful garden ornamental trees. It has strong resistance to soot and sulfur dioxide and is an excellent anti-pollution tree species. Seeds are used as dried fruits. Leaves and seeds can also be used in medicine. Endangered species: rare protection level: this species has been listed as a national first-class protected wild plant (approved by the State Council 1999 on August 4th). West Tianmu Mountain in Zhejiang Province is one of the nature reserves in China, and the harvesting of wild ginkgo in this area should be strictly prohibited. On the steep rock wall at an altitude of 1000 meters, the trunk of an ancient ginkgo tree with five generations living under one roof is regenerated from the trunk and the trunk base, and reinforced with stones. The scattered ancient ginkgo trees in China should also be protected; Many provinces and regions have cultivated it. [Edit this paragraph] Cultivation points of Ginkgo seedling propagation. The embryo is dormant. Sow in winter or early spring after stratification. When the height of seedlings exceeds 1 m, they can be planted. Male trees should be selected for street trees. It can also be propagated by cutting and tillering. In order to promote early fruiting and cultivate excellent clones, bud grafting or branch grafting can be used for propagation. Ginkgo biloba is the oldest seed plant in relict plant. It takes more than 20 years from planting to fruiting, and after 40 years, it can bear a lot of fruits and live to be over 1000 years old. Ginkgo biloba is a deciduous tree, which blooms in May and matures in 10, and its fruit is orange-yellow drupe. Ginkgo biloba was originally distributed all over the world, but only remained in the subtropical mountainous area of China after the Quaternary Glacier. At present, the distribution of Ginkgo biloba mostly belongs to artificial cultivation areas. Some improved varieties of South Carolina mainly cultivated in China, France and the United States are introduced as follows: Anyin 1 Dammaling: 268 seeds per kilogram, with a seed rate of 28% and a seed rate of 78%. The output of projected area of crown is 2.7kg/m2. Sweet and waxy, with high yield and good quality. Giant Buddha Hand: The main local species in Dongting Mountain area of Jiangsu Province. The seeds are oval, about 2.88 cm long and 65438 0.73 cm wide, with 300-350 seeds per kilogram. They are sweet, waxy, high-yield and high-quality. Dayuanling is the main variety planted in Tancheng, Shandong Province. The fruit is spherical, brownish white, translucent and oily when it is ripe. Single grain weight11.8-15.7g, with 64-85 grains per kg. The seeds are ovoid, with a single grain weight of 2.97-3.75g, 266-366 grains per kg, and the kernel yield. Xiaoyuanling: As a specialty of Dafeng Forestry Base in Jiangsu Province, it not only supplies fruits all the year round, but also tens of thousands of ginkgo trees for greening. It is one of the protected areas of China Ginkgo Base. [Edit this paragraph] Economic value Ginkgo biloba, also known as ginkgo, belongs to the category of dried fruits, and its economic achievements can last for thousands of years. Among many dried fruits, Ginkgo biloba ranks third in economic value. The value of ginkgo biloba is mainly reflected in food and medicine. China's ginkgo production accounts for 90% of the world's total output. Ginkgo biloba and ginkgo biloba are important products to earn foreign exchange through export, especially important pharmaceutical raw materials for preventing and treating hypertension and heart disease. Ginkgo biloba extract can protect the heart and brain. There are 160 kinds of known chemical extracts of Ginkgo biloba. There are mainly flavonoids, terpenoids, phenols, alkaloids, polyisoprene, quinic acid, linoleic acid, python oxalic acid, ascorbic acid, α-hexenal, bilobanol, bilobanone and so on. The medicinal use of Ginkgo biloba is mainly reflected in medicine, pesticides and veterinary drugs. Ginkgo biloba was listed as a royal tribute in the Song Dynasty. Japanese people have the habit of eating ginkgo every day. Westerners must eat ginkgo at Christmas. As far as eating methods are concerned, Ginkgo biloba mainly includes fried food, baked food, cooked food, side dishes, cakes, candied fruit, canned food, beverages and alcohol. In the Ming Dynasty, Li Shizhen once said: "Entering the lung meridian can benefit the temper, stop asthma and cough, and reduce defecation." Ginkgo biloba in Ben Feng Jing Yuan written by Zhang Lulu in Qing Dynasty has the effects of resolving phlegm, detoxicating and killing insects, and can be used to treat "furuncle, ulceration of mammary abscess, dental caries, infantile diarrhea, leucorrhea with red and white discharge, chronic stranguria, nocturnal emission and enuresis". In the Ming Dynasty, Chinese patent medicines made of Ginkgo biloba appeared in Jiangsu, Sichuan and other places for clinical use. It has the functions of astringing lung and relieving asthma, and is mainly used for treating excessive phlegm, asthma, cough, nocturnal emission, leukorrhagia and frequent urination. Ginkgo biloba exocarp contains a lot of hydrogenated ginkgolic acid and ginkgetin. Ginkgo biloba leaves have the function of regulating respiratory organs, and the water-soluble components of exocarp have good antitussive and expectorant effects, similar to cyclophosphamide and dexamethasone. Ginkgo biloba leaves contain ginkgolic acid, which has a strong inhibitory effect on mycobacterium tuberculosis and dermatophytes, so it can be used to treat tuberculosis and dermatoses. The effective rate of epicarp alcohol intermediate in inhibiting 22 common clinical pathogenic fungi was 865438 0%. 0. 1% hydrogenated ginkgolic acid inhibited 25 clinical pathogenic fungi with an effective rate of 92%. Ginkgo biloba leaves have important medicinal value. Ginkgo biloba, bitter and astringent, contains biflavonoids. It has been proved by experiments and clinic that it can reduce serum cholesterol and dilate coronary artery, and has certain auxiliary treatment effect on coronary heart disease and hypertension. In 1960s, the Institute of Botany, Chinese Academy of Sciences and other units developed Shuxuening injection with Ginkgo biloba leaves, which has certain curative effects on coronary heart disease, angina pectoris and cerebrovascular diseases. The inhibitory rate of Ginkgo biloba exocarp extract on apple anthracnose and other plant pathogens was 88%- 100%. The control rate of ethanol extract on geometrid reached 100% within 3 days, and it also had control effects on Tetranychus urticae, Myzus persicae, Chilo suppressalis and other pests. According to Compendium of Herbal Medicine of Folk Veterinary Medicine, Ginkgo preparation can treat strain of livestock, nasal congestion, lung abscess, cough due to lung deficiency, blood drop in urine, leucorrhea of female livestock, etc. Dingchuan decoction developed by Shandong Animal Husbandry Medical Station is used to treat infectious laryngotracheitis in chickens, and the cure rate is 95%. Ginkgo biloba leaves can also be used as pesticides. 1kg leaves add 20kg water, boil for 30min, and then soak for 2-3 days. The control rate of spiders and Pieris rapae is over 90%, and there is no residue. Using the effective chemical components of Ginkgo biloba leaves and its special medical and health care functions to produce health food, medicine and cosmetics is attracting the attention of research, development and production units at home and abroad. Many enterprises in various countries compete to develop and produce natural green products with ginkgo as raw materials to replace synthetic chemicals that have great side effects on human health. There are 20,000 kinds of ginkgo beverage, ginkgo peach juice, ginkgo beer, ginkgo tea and other health products developed from ginkgo leaves in Dafeng Ginkgo Base, Jiangsu Province. Pizhou City, Jiangsu Province is in the forefront of the world in the planting and processing of Ginkgo biloba extract. Ginkgo biloba and ginkgo biloba leaves are used to make healthy pillows. It is recorded in Pillow Book that precious Chinese herbal medicines such as Ginkgo biloba leaves for more than three years are selected to make healthy pillows. It is light and fragrant, and can improve the quality of human breathing and sleep. Long-term administration can prevent cardiovascular diseases, prevent hypertension, stroke and diabetes caused by vascular aging in adults, and make adults, especially middle-aged and elderly people, maintain normal cardiac output and normal nervous system function, and maintain normal cell life cycle as much as possible. Ginkgo trees are tall and straight, and wood is a high-grade material for making musical instruments and furniture. Ginkgo wood is of high quality and low price, and is known as "silver fragrant wood" or "silver wood". Ginkgo wood has luster, straight texture, fine structure, easy processing, no cracking, strong corrosion resistance, easy painting, low nail digging power, special medicinal flavor and strong insect resistance. Ginkgo wood can be used to make carved plaques, wooden fish and other handicrafts, and can also be used to make high-end furniture such as cabinets and desks. Ginkgo biloba has the characteristics of singing, guiding sound and elasticity, and is an ideal material for making musical instruments It can be used to make surveying and mapping instruments, pens and other cultural goods, and it is also the first-class wood for making chessboards, chess pieces, sports equipment, seals and small handicrafts. In industrial production, silver wood is most suitable for making machine models and wooden models of X-ray machine filter plates, textile printing and dyeing rollers, bodiless lacquerware, plywood, chopping boards and wooden telephones. Ginkgo biloba is recognized as an economic tree species with greening, beautifying environment and ornamental value. Ginkgo trees are magnificent in appearance, beautiful in leaf shape, long in life and few in pests and diseases. They are most suitable for shade trees, street trees or street trees. It has good ornamental value. Ginkgo biloba is lush in summer and golden in autumn, giving people a handsome, gorgeous, luxurious and elegant feeling. Therefore, ginkgo biloba is regarded as an important tree species in courtyards, sidewalks and gardens at all times and in all countries. When ginkgo biloba is used for street greening, male plants should be selected to avoid polluting pedestrians' clothes. Dandong is the first city in China to use Ginkgo biloba as a street tree. Note: Ginkgo biloba leaves should not be drunk with tea and chrysanthemum. Ginkgo biloba contains a lot of ginkgolic acid, which is toxic. Generally, the leaves bought are not extracted by deep processing, and the ginkgolic acid content in them is as high as 3000-4000ppm. In particular, ginkgolic acid is water-soluble. Instead of eating ginkgo brass, ginkgolic acid and other effective substances inside, the effect is the opposite and toxic! In medicine, especially in ginkgo products used in hospitals, slight ginkgolic acid containing 10ppm is allowed! [Edit this paragraph] Ecological value Human beings have a late understanding of the ecological value of Ginkgo biloba. The highest level of Ginkgo biloba value-ecological value, is priceless! The ecological benefits of Ginkgo biloba are mainly reflected in: from the perspective of cultivation, Ginkgo biloba belongs to fruit trees-dried fruits; Belongs to forest trees-timber trees, protective trees, insect-resistant trees, long-lived trees and pollution-resistant trees. Ginkgo biloba is an ideal tree species for fast-growing and high-yield forest, farmland shelterbelt, road shelterbelt, bank protection forest, beach shelterbelt, village shelterbelt, forest-grain intercropping and "four sides" greening. It can not only provide a large number of high-quality wood, leaves and seeds, but also green the environment, purify the air, conserve water and soil, control pests, adjust temperature and psychology. It is a good tree species for afforestation, greening and ornamental, which is of great significance to the adjustment of agricultural and forestry planting structure in the north and south of China and the forestry development in plain agricultural areas. First, the green environment ginkgo is resistant to pests and diseases. It is recognized as a pollution-free tree species and the most ideal tree species for ornamental greening. Parks, gardens, communities, roadsides, urban greening and ginkgo planting can be described as "once and for all". Second, purifying the air Ginkgo biloba has the functions of preventing pollution, fireworks and dust. Ginkgo trees can be planted in industrial areas, residential areas, towns, densely populated areas and rest areas. According to a certain proportion, ginkgo forest area and ginkgo forest belt will be formed to naturally purify the air, reduce the content of suspended solids in the atmosphere and improve the air quality. Third, maintain soil and water Ginkgo has the functions of conserving water, preventing wind and fixing sand, and maintaining soil and water. In areas where deforestation, soil erosion and sandstorm erosion are serious, ginkgo shelter forest, shelter forest, road shelter forest, bank protection forest, beach shelter forest, sand prevention forest, etc. Planting is to maintain soil and water and improve the ecological environment. 1996 Puding County, Guizhou Province takes planting ginkgo biloba and developing ginkgo biloba industry as the road to get rid of poverty and become rich. The soil erosion in this county is serious, even a handful of soil should be planted with a corn, and the ground is covered with carboniferous azithromycin particles. In order to prevent soil erosion, farmers planted Ginkgo biloba, which not only improved the ecological environment, but also generated economic income (Ginkgo biloba leaves were sold to processing plants). Nowadays, Ginkgo biloba has been regarded as a new way to get rid of poverty and become rich in Dabie Mountain, Daba Mountain, Yimeng Mountain and other old, less and marginal areas, that is, planting Ginkgo biloba, improving the ecological environment and forming an industrial economy, which has multiple benefits. 4. Pest control Ginkgo biloba can kill crop pests and diseases, especially cotton, spider mite, peach aphid and Chilo suppressalis. Planting ginkgo around agricultural areas is the natural enemy of crop pests and protects crops. V. Adjusting the temperature Ginkgo trees have special functions of being warm in winter and cool in summer. In midsummer, the palm of your hand will feel cold when touching the trunk of Ginkgo biloba, and it will feel hot when touching other trunks (willows). According to the measurement, in midsummer, when the direct sunlight reaches 40.2 degrees Celsius, the temperature under the ginkgo tree is 35.3 degrees Celsius, and the temperature difference between the temperature and the shade of the ginkgo tree is 4.9 degrees Celsius, while the temperature difference between weeping willows is only 2.3 degrees Celsius. The temperature adjustment ability of the ginkgo tree is more than twice that of the willow tree. Therefore, the construction of ginkgo forest area and ginkgo forest belt will form a scale, which will cause the climate of the community and have a good impact on regulating the temperature of farmland and residential areas and improving the climate. The artistic value of ginkgo biloba is magnificent, and its trunk is winding and lush. In the famous mountains and rivers and ancient temples in China, there are tall and straight ancient ginkgo biloba. They go through vicissitudes, trace back to ancient and modern times, and give people a sense of mystery. Poets and poets of past dynasties set foot in temples and left many poems and songs, proud of their beautiful scenery and merits. Ginkgo biloba with graceful posture is selected and processed into bonsai, and the majestic posture of Ginkgo biloba in nature is concentrated in the basin. It is elegant and interesting, and it is clear to the desk, which makes people feel happy. Ginkgo biloba is a famous long-lived tree species, with strong vitality, peculiar leaf shape and easy grafting, reproduction and pruning. It is a high-quality material for making bonsai. Ginkgo bonsai made of ginkgo milk is a must, with high ornamental value and economic value. Ginkgo biloba is a common tree species in bonsai in China. Ginkgo bonsai has become a must among China bonsai because of its thick stems, bent branches, exposed roots, unique shape, vigorous and unique taste. Summer is lush, and autumn is golden, giving people a feeling of precipitousness, grandeur and elegance. In recent years, people pay more and more attention to it, and it is known as "living art sculpture". According to people's different appreciation requirements, there are several types of bonsai, such as ornamental bonsai, foliage bonsai and stump bonsai ... [Edit this paragraph] Prose-Ginkgo biloba, I miss you, I don't know why you are also called Gongsun Tree. But most people call you ginkgo, which is easy to understand. I know, your characteristics are not only that you have this apricot-like fruit, the skin is as white as silver and the nucleolus is rich in nutrition-needless to say, this is enough for your characteristics. But most people don't know that you are the oldest and most advanced flowering plant. Your pollen and ovules behave like animals, and you are a treasure preserved by human beings. You can't exist in nature, but you still stand upright, singing the triumph of human victory in space. Saint of the East, a living monument to China culture. You are only in China, and most people don't seem to know it. I have been to Japan, and Japan has you, but you are obviously an overseas Chinese in Japan. China culture has existed in Japan for as long as you have lived in Japan. You really should be called the national tree of China. I like you. I like you very much. But it's not because you are a specialty of China that I particularly like it. Because you are beautiful, true and kind. How straight your stems are, how vigorous your branches are, how green, how clean and how delicate your fan leaves are! In summer, how many temples have been crowned with towering clouds, and how many working people have been crowned with cool canopies. Although the phoenix tree has your straight end, it is not as strong as you; Poplar is lush but not solemn. The smoky wind will charm you, and birds will come to song for you; God is a hundred gods-if there are gods, I believe that whenever the moon is empty, they will come to your feet for a party. Autumn comes, butterflies die, your green leaves will turn golden yellow, and butterflies will fly out of the garden. Aren't you a clever magician? But you don't have the kind of Jianghu atmosphere that makes people hide their noses. When you are free from everything and your branches are propped up in space, you are not ashamed of the cold wind, frost and snow. How rough and free and easy, I'm afraid there hasn't been a monk like you since Buddhism. You didn't give in to your attitude at all, but you didn't despair; Your virtue is as barren as music, but you are not proud; Your taboo seems to be "detachment". You care about all the vegetation, you care about everything, but you don't hide it. Isn't your fruit nourishing people, your sturdy wooden equipment, or your fallen leaves an excellent fuel for starting a fire? But I am really a little strange: strangely, everyone in China seems to have forgotten you for a long time, as if it had started from ancient times. I can't find your name in China's classics. I seldom see China poets praising your poems, and I seldom see China painters describing your paintings. What the hell is going on here? You are the eternal witness of China culture. Don't you find it strange? Ginkgo biloba, the people of China have forgotten you. Although everyone is eating your ginkgo, everyone likes to eat your ginkgo, but I really forgot about you. There are people in the world who can't tell, but they have never forgotten your example for so long. Really, isn't the capital the first good area? But I seldom see your shadow; Why are acacia trees all over the street and eucalyptus trees all over the garden? I miss you so much, Ginkgo! I hope you don't forget China. A little dangerous. I am afraid that if you are unhappy, you will disappear from the land of China. In the airspace of China, you will never hear songs praising life. Ginkgo biloba, I really hope that one day people in China will worship you more, because they can eat more ginkgo biloba.
