Richun Co., Ltd., a well-known tea brand, was established in 1993, a famous trademark in Fujian, and a large-scale specialized enterprise integrating tea base construction, tea, tea utensils, and tea food development, production and sales

During the Qianlong period of the Qing Dynasty, the ancestor of Richun Wang Shirang accidentally found a different tea tree, picked it into tea and presented it to the Qianlong Emperor, the emperor greatly appreciated it after drinking, and then gave the name "Tieguanyin". Since then, the descendants of the Wang family have adhered to the family ancestral motto of "humility, courtesy, and truthfulness", and have inherited the tea-making skills of Tieguanyin from generation to generation. After the reform and opening up, Wang Shirang, the eighth generation of Sun Wang Muqi, founded the Nanshan Tea Processing Factory. In 2008, the ninth-generation Sun was transformed into Richun Joint Stock Company.

On the basis of inheriting the tea-making skills of the ancestors, Richun Co., Ltd. has always been exploring a road of Tieguanyin standardization: it has successively established three Tieguanyin scientific research bases in cooperation with Peking University, Wuyi University, and Anxi Tea College of Fujian Agriculture and Forestry University, from which the Tieguanyin planting and production standards have been extracted, and a product traceability system has been established to control food safety. In addition, the company also regularly holds the Tea King Competition every year to encourage the improvement and development of tea-making technology, and realize the standardized operation of tea gardens at the source; In order to standardize production, the company has built a non-secondary pollution workshop, introduced the world's leading food production line, invested heavily in the establishment of a national laboratory, and set up a review system with blind evaluation by more than 5 national first-class tea assessors. In 2013, Richun also participated in the formulation of national standards for oolong tea production, which became a model of industry standard production in one fell swoop. In 2008, Richun Co., Ltd. established the "Richun Management College", established a standardized training system, cultivated a large number of outstanding talents for the tea industry, and was known as the "Whampoa Military Academy of the tea industry" by the society.
