The remains and relics left over by history, as the products of history, are branded with the times. From this perspective, the remains and relics left over from history have historical value, which is the primary value of cultural relics. Any historical sites and cultural relics are created by the scientific level at the time of production, which itself contains or reflects the scientific and technological level at that time, and reflects the social, political, economic, military and cultural conditions at that time from a certain aspect. Therefore, on the whole, cultural relics are historical remains with historical, artistic and scientific values. As an inseparable whole, the three exist in the material and cultural heritage, permeating and restricting each other. As far as a relic or relic is concerned, it does not all have three values, but it generally has historical value and artistic or scientific value. An immovable cultural relic, if composed of several individuals, is rich in content and generally has historical, artistic and scientific value. And every object, not all.
Therefore, the so-called value does not mean that ancient objects are valuable.
Is the value of ancient tin ware high or not? There are many kinds of tin ware (tin crafts), with high or low tin content and good or bad quality. So how to tell the good from the bad when buying tin ware?
Distinguishing tin ware pays attention to "sound, color, quality and workmanship"
Smell its "sound" first: pure tin has good ductility, so it is called "ringing tin" because of its distortion and sound. Handicrafts are distorted, so you can't use this method when you buy them. You can use a simpler method to "smell the sound": gently sweep the tin ware from your palm with your nails, and 97% of the alloy tin ware has a clear metallic sound and a short echo; 99.9% of the tin sound is neither crisp nor bright, and there is no echo. It is a first-class tin ware. The book Dian Bu records that "only Mengzi tin is famous in the world ... its factory name is old. Old tin will ring. "
Then look at its "color"
Pure tin, color as silver, bright as a mirror! After polishing, 97% of the tins are bright and not white, which belongs to dark brightness. After polishing, 99.9% of the tin ware presents bright silver, which belongs to the first-class tin ware and looks like silverware. In modern times, the "spot tin" originated in Gejiu, Xi Du, which is characterized by a purity of 99.9%. In addition to the "silver" polished, it can also present the texture effect of black, white and gray, making the tin ware exquisite and colorful, and it is a beautiful tin ware.
Third, distinguish its "quality".
Quality refers to the purity of tin ware. The higher the purity of tin ware, the more durable it is. Packaged food is not only harmless, but also can keep fresh for a long time. Low-purity tin products are perishable and unfit for eating. Most of the imported tin wares are marked with purity, while most of the domestic tin wares are not, but we can know their source slightly. In Malaysia, Thailand, Singapore and other places, the tin content is mostly 97%, claiming to be pure tin; 99.9% of all tin vessels in the world are produced by the old method, that is, pure tin in the true sense, or high-purity tin and refined tin. If the content is less than 97%, it belongs to tin riding device, and its practical value and collection value are not high, so it is not recommended to buy it.
Reward his "work" in the future.
Work refers to the processing of tin ware. The process of tin ware depends largely on its purity. 97% and below tin ware is hard and suitable for machining. The processed tin ware is often integrated and has obvious relief effect, but its sealing is not the best. Therefore, tea cans are generally designed with two layers, inside and outside. 99.9% of the cans are soft in texture and have strong handmade characteristics. A work is composed of several parts, which can show a high level of carving and hollowing out technology. High purity tin has good sealing performance. You only need a shell to achieve this effect. You can often find that it will bounce back when you cover it hard. That's the reason.
Then there is "price". Tin itself is a precious metal, and every finished product should have its value. If the retail price is too low, this product is suspected of alloy tin, which is a safety hazard!
What kind of animal's liver is delicious and has high nutritional value? When it comes to animal liver, people may think of goose liver, which is known as the three most delicious foods in the world, and chicken liver, duck liver and pig liver that are often eaten in daily life. Liver is an important organ for storing nutrients in animals, which is rich in nutrients, but it is also the main detoxification organ in animals, containing a lot of cholesterol. How to eat liver is scientific and reasonable? What are the nutritional components of goose liver, chicken liver, duck liver and pig liver? With these questions, the author interviewed Ma Wenjun, deputy chief physician of Nutrition Department of Guangdong Provincial People's Hospital. Ma Wenjun said that the liver is an important organ for animals to store nutrients. It is rich in nutrients, such as iron, and is a common food in blood-enriching foods. The content of vitamin A in animal liver is far more than that in milk, eggs, meat, fish and other foods. It has the functions of maintaining normal growth and reproductive function, protecting night vision, and preventing dry eye and fatigue. At the same time, animal liver also contains vitamin B2 and various trace elements. Is the animal's liver particularly nutritious? Director Ma said that in fact, the nutritional value of several common animal livers on the market is not much different. Every 100g of liver, as far as protein is concerned, bovine liver contains about 20g, pig liver about 19g, chicken liver about 17g, duck liver and goose liver about 15g. As far as fat is concerned, the content of beef liver is about 4g, pig liver is about 5g, chicken liver is about 5g, duck liver is about 8g and goose liver is about 3g. The liver is also rich in vitamin A, vitamin B 1 and vitamin B2. Edible animal liver should be properly cooked with pig liver, chicken liver, duck liver and goose liver, which is not only delicious, but also provides sufficient nutrition for the body and is a good food source to maintain health. However, some citizens believe that the liver is the main detoxification organ in animals and contains high cholesterol, so they dare not eat animal liver. Ma Wenjun said that for the human body, it is best not to consume more than 300mg of cholesterol every day. Cholesterol content per 100g animal liver is: pig liver contains 266mg of cholesterol, bovine liver contains 297mg of cholesterol, chicken liver contains 356mg of cholesterol, duck liver contains 34 1mg of cholesterol, and goose liver contains 285. Excessive consumption of animal liver may lead to the accumulation of cholesterol and vitamin A in consumers. When the elderly are complicated with cardiovascular diseases and have high cholesterol, the animal liver is not suitable for this group of people. Adults eat no more than 100g (200 g) of animal liver every week, which can not only meet the human body's demand for vitamin A, but also have no great influence on blood cholesterol. Animal liver must be eaten fresh, washed carefully and repeatedly before eating, soaked in water for a period of time, and then cooked. You can also cut the liver into pieces, scrape it gently in a basin, then rinse it clean and cook it. Director Ma stressed that animal livers should never be cooked in pursuit of freshness, and cooking time should be as long as possible to ensure food safety. The nature of vitamin A contained in the liver is relatively stable, so there is no need to worry about being destroyed by excessive washing and long-term cooking. At the same time, Director Ma also pointed out that animal liver is a good blood-enriching food, especially for some women and children suffering from iron deficiency anemia. Eating a proper amount of animal liver can achieve a certain blood-enriching effect. Guangdong people who love to drink soup prefer to drink soup instead of eating slag when cooking soup with animal liver. Director Ma stressed that people who need iron supplementation should not only drink soup, but also eat animal liver as soup residue, because more nutrients are still in the soup residue.
People eat the liver, lungs and hearts of animals, but the nutritional value is not high. They are rich in protein, vitamins A and B, iron, zinc, selenium and other minerals, with high nutrition, but high cholesterol, and may accumulate some toxins, so they should not be eaten more.

Why is the value of goods leaving the logistics park higher than that entering the park? Four parks and four centers are the focus of Chengdu logistics system.
Planning first and guiding urban construction with scientific planning are important laws to promote rapid economic and social development. Aware of the importance of planning, Chengdu has continuously revised and improved its modern logistics development plan according to the new round of overall urban planning, comprehensive transportation planning and industrial layout planning, and put forward the key points of "one network and two platforms (logistics fast network, public logistics information platform and transportation infrastructure platform), four parks and four centers (four logistics parks and four logistics centers) and fifty logistics service stations".
"One network"-that is, focusing on opening five trains of railway freight, international direct flights, domestic intercity freight buses and centralized distribution in regional cities, and constructing a fast logistics channel connecting Chengdu with the world freight hub cities, domestic developed regions and central cities and radiating major cities in the western region.
The "second platform" is to build a public logistics information platform and a transportation infrastructure platform. Focusing on the establishment of a large customs clearance information system, aiming at integrating logistics information resources and improving logistics efficiency, building a public logistics information system; Focus on promoting the construction of the second runway of the airport and the container central station, with the western hub airport and the western railway hub as the core, speed up the integration of road freight stations, improve the supporting roads of logistics parks and logistics centers, do a good job in the construction of freight roads and bypass roads, and promote the connection between Chengdu and neighboring provinces and cities.
"Four Parks and Four Centers" means to build four international hub logistics parks and four regional comprehensive logistics centers based on Chengdu's main railway, aviation and highway freight facilities.
The four parks refer to: relying on Chengdu Shuangliu International Airport, building Chengdu International Aviation Logistics Park near the international and domestic cargo terminals of the airport, radiating the western region and even the whole country, connecting major cities at home and abroad, and providing aviation logistics services for goods with high added value and strong timeliness; Relying on Chengdu Railway Container Center Station, Chengdu International Container Logistics Park will be built next to Chengdu Railway Container Center Station, radiating to the west, connecting ports and major cities across the country, and providing logistics services such as multimodal transport, warehousing and distribution, transit and distribution, unpacking, processing and packaging, and information services for container goods. Relying on the bulk cargo terminals of Chengdu Railway Hub (Qingbaijiang Dawan Freight Terminal and Xinjin Puxing Freight Terminal), Chengdu Qingbaijiang Railway Bulk Logistics Park and Chengdu Xinjin Railway Bulk Logistics Park will be built next to Qingbaijiang Dawan Railway Station and Xinjin Puxing Freight Terminal, radiating southwest, connecting major domestic cities and mainly handling railway bulk cargo business.
"Four Centers" refers to the construction of a regional comprehensive logistics center that radiates the greater Chengdu economic circle in the east, south, west and north directions, relying on the Chengdu radial expressway network, in addition to the expressway around the city. Relying on Chengdu-Mianyang Expressway and Sichuan-Shaanxi Road in the north of the city, a new capital logistics center will be built next to the freight road to provide regional intercity distribution and regional urban distribution services for the freight road transportation in Chengdu-Mianyang-Sichuan-Shaanxi Economic Belt; Relying on Chengdu-Chongqing Expressway and Chengnan Expressway in the east of the city, Longquan Logistics Center will be built in Chengdu National Economic and Technological Development Zone outside the Ring Expressway to provide public water transportation, intercity distribution, urban distribution and other logistics services for Chengdu-Chongqing Economic Belt and East Sichuan-South Economic Zone; Relying on Le Cheng Expressway, Chengya Expressway and Chengnan Expressway, the Shuangliu Highway Logistics Center will be built in the Shuangliu section of the expressway around the city, radiating Leshan, Ya 'an, Panxi Economic Zone and Tibet and Yunnan, undertaking the logistics distribution in southern cities and providing logistics services for road transport goods in southern cities and Yunnan-Tibet areas; Relying on Chengdu Export Processing Zone, a regional professional Chengdu Bonded Logistics Center radiating processing trade enterprises and import and export goods in the western region will be built beside the Chengdu-Guancheng Highway outside the Ring Expressway to provide logistics services for import and export goods and bonded goods in the western region.
"Fifty logistics service stations"-refers to the construction of supporting logistics service stations near large-scale professional trading markets, urban commercial concentration areas, industrial concentration development areas, large-scale industrial production enterprises and major transportation facilities to provide personal logistics services. Control the total number and construction scale of logistics service stations to prevent repeated construction. In principle, the number of 20 10 logistics service stations should be controlled at about 30, and in 2020 it should be controlled at about 50.
Among them, the construction of four major logistics parks and four major logistics centers is the focus of this system.
