Anji County Dashanwu Tea Farm was founded in 1980, and its founder is Sheng Zhenqian, who is known as "the first person in Anji white tea". In 1981, Sheng Zhenqian, then a technician of the County Forestry Institute, cut branches from the Daxi White Tea Ancestral Tea Tree and successfully cultivated a new variety of Anji White Tea through the asexual cuttings breeding technology. Until 1999, the area of the white tea garden reached more than 300 acres, and a complete set of planting, picking, frying and sales systems were formed. Today, Dashanwu is one of the most valuable brands of Anji white tea, with its own tea garden of 1,300 acres, and has passed a number of certifications such as the pollution-free agricultural product base of Zhejiang Province, the green food of the Ministry of Agriculture and the national good agricultural practice GAP, and has built a high-standard clean production and processing plant, with an annual output of about 30,000 catties. In addition, Dashanwu has also won many honors and titles such as Zhejiang Provincial Demonstration Tea Factory, Anji County White Tea Standardization Demonstration Garden, and provincial and municipal famous trademarks.
 
The unique whitening mechanism of Anji white tea tree, the young buds and leaves of spring tea are jade white, and Anji white tea is made from the whitest bud and one or two leaves on the tea tree, and the name "white tea" is also derived from this. As the temperature rises, the leaf color returns to green, so the picking time of Anji white tea is only about 20 days in spring, concentrated around Qingming and Guyu. Dashanwu is located in Xilong Village, Anji County, the core protection area of Anji White Tea Tea Garden, the place of origin, using the fresh leaves of the excellent tree species "Baiye No. 1" as raw materials, fried by experienced masters, and the steps of arranging, finishing and rolling are completed by automated equipment to ensure stable tea quality.
