From the Third Plenary Session of the Eleventh Central Committee to the early 1980s, the sericulture area of ​​the county has grown to 7,000 mu, distributed in Zhen'an Town, Baishi Town, Gaocun Town and other places. In the 1990s, more and more farmers changed from traditional rice cultivation and peanut cultivation to mulberry cultivation. After the approval of the State Council in 1996 to establish Yun'an County, the county party committee and county government in order to increase the development momentum of Yunan sericulture, the Yunan sericulture planting is collectively referred to as "Yunan silkworm cocoon." Under the favorable situation, the county government has widely mobilized the masses to develop and utilize the vast river beaches and slopes on both sides of the county rivers to replant sericulture, and to adjust the sericulture, sericulture and sericulture around the sericulture area, and to plant sericulture. The two sides of the strait gradually extended to the village committees, and centered on Zhen'an Town, Baishi Town and Gaocun Town, and radiated the other village committee farmers to grow mulberry sericulture. At present, the sericulture area of ​​Yunan grows by 88% every year, gradually It forms a pillar industry of the agricultural economy centered on Zhen'an, Baishi, Gaocun and other towns, and has become a shortcut for farmers to become rich.
