Yongan Town is located in the northwest of Xishui County, about 35 kilometers away from the county seat, with an area of 1 19.3 square kilometers and a population of 26,000. It has jurisdiction over four villages, one residence and 46 villagers' groups, bordering Mashan Town, Xihe Township, fuxing town and Xieba Township in Zheng 'an County. The average elevation of this town is 900 meters, and it is mountainous and hilly. Affected by subtropical monsoon humid climate and vertical climate, Yunnan-Guizhou Plateau has no severe cold in winter, abundant rainfall and heat in summer, and four distinct seasons.

Per capita arable land area 1. 1 mu, per capita income of farmers 1.700 yuan. Industrial Structure Yong 'an Town has nearly10.5 million mu of "zinc-rich and selenium-rich" tea gardens, and there are 6 tea processing plants without industrial, chemical fertilizer and pesticide pollution. The "Xianrenling" zinc-rich and selenium-rich tea produced in this tea area won the gold medal of 194 "China Modern Consumer Goods Quality Appraisal and Best Quality Health Care Boutique".

Based on the actual situation, Yongan Town adheres to the development strategy of "building an ecological home and developing green industries", and strives to implement the "four greens" project, that is, taking creating a green environment, establishing a green base, implementing green processing and building a green brand as the breakthrough point, it puts forward the 16-character working idea of "stabilizing grain and increasing oil, breaking through smoking pigs, expanding tea leaves and developing medicinal peppers", and unswervingly promotes the adjustment of agricultural structure and expands the scale of the base. Tianqiao Township is located at the southern end of Fenggang County, more than 70 kilometers away from the county seat. It is the most remote and remote township in our county, and is known as "Fenggang Tibetan". The township has jurisdiction over 3 village committees, 1 neighborhood committee, 58 villagers' groups and more than 5,400 households, with a total population of more than 23,000 people, with a total area of 152 square kilometers and cultivated land area of 2. Because of the great difference in relative altitude, the highest altitude is 1362 meters, so there has always been a natural climate of "one mountain with four seasons and ten miles of different days". Every summer, when people in the city are worried about the scorching sun, the overpass surrounded by mountains is still chilly, so Yang Jiao can't exert its scorching power in this green town, which makes people feel the beauty of being in a holiday resort. The continuous mountains not only blocked the scorching sun, but also created a unique landscape for the overpass. About 500 acres of tea garden behind the township government hides an amazing stone forest group. Some of them stand proudly, like a sword across the sky, some hang their heads, just like a shy and smiling gentle girl, and some stand opposite each other, strewn at random, forming a natural stone gate. If you stand on the dam of Chashan Mountain, enjoying the unique scenery and the cool breeze, you have to sigh the creator's eccentricity, the stone forest hidden in the leaves of green tea, and people can't help wondering whether any passing fairies touched the trace when flying over here.
