After liberation and from the early days of reform and opening up to 1982, because tea was a material purchased and sold under the planned economy era, the tea produced by the Lao Xie family in the production team was sold to the Qiashe Tea Purchasing Station. The tea is transported to the Shexian Tea Company from the purchasing station and delivered to the Shexian Tea Factory for refining and processing for domestic and export sales. In 1983, with the reform and opening up, joint production contracting was implemented, tea gardens were distributed to households, and tea farmers were allowed to produce and sell tea by themselves.

Forty Xie, the 49th direct descendant of the Xie family, has been influenced by his ancestors' skills in making Huangshan Maofeng since childhood. He became a tea farmer after graduating from high school in 1973. He received careful instruction from the older generation of tea farmers, carefully studied and mastered the cultivation of tea trees, the management of tea gardens, and the production techniques of Huangshan Maofeng. In 1987, Huangshan Guangming Tea Factory was the first to be established in Huizhou District. While inheriting the traditional skills of Huangshan Maofeng, the Huangshan Maofeng Maofeng tea made with traditional skills was processed through circular sieves, shaking sieves, winnowing, machine sorting and other processes. Refined Huangshan Maofeng tea and put it on the market. In 1993, the "Qianqiuquan" trademark was registered, and the "Qianqiuquan" brand Huangshan Maofeng has successively passed green food and organic food certifications. In 1994, it was the first company in Huangshan City to break the traditional picking rules. It started to mobilize tea farmers to pick a large number of fresh buds and leaves before the Qingming Festival, and introduced famous and high-quality tea equipment. It integrated the traditional skills of Huangshan Maofeng and successfully developed a new mechanized processing of Huangshan Maofeng. After inheriting Industrial production has been realized on the basis of traditional techniques, which has greatly improved the color, aroma, taste and shape of Huangshan Maofeng. In 2005, in order to inherit the method of making Huangshan Maofeng from our ancestors, we registered the trademark "Lao Xie's Tea". In 2006, we built a new Huangshan Maofeng processing and clean standardized factory. While inheriting the traditional skills, we also realized the automation, cleanliness, and production of Huangshan Maofeng. Environmentally friendly new process production. In order to create high-quality Huangshan Maofeng products, we developed the "Huangshan Maofeng Tea Flavoring Machine" with independent intellectual property rights. In 2008, it obtained the national utility model patent. Based on the traditional bamboo cage charcoal fire slow baking, this machine uses the original ecology of wood and bamboo. The material and hot air principle re-bake the Huangshan Maofeng tea to enhance the aroma, which not only further improves the color, aroma and shape of Huangshan Maofeng tea, but also maintains the traditional flavor of Huangshan Maofeng tea. The innovative process of Huangshan Maofeng green tea won the national invention patent in 2010. Xie Shisi is now a tea-making engineer, associate researcher, and the sole inheritor of the national intangible cultural heritage Huangshan Maofeng.
