Sichuan Qianyuan Traditional Chinese Medicine Decoction Pieces Co., Ltd., as a "Guanghan time-honored brand", can trace its history back to 1926 (the 15th year of the Republic of China) as a traditional Chinese medicine decoction piece processing workshop, and has undergone nearly a century of inheritance and development. In 1954, a traditional Chinese medicine processing factory was established. In 1998, it was renamed Sichuan Guanghan Traditional Chinese Medicine Pieces Co., Ltd. In 2015, it was officially renamed Sichuan Qianyuan Traditional Chinese Medicine Pieces Co., Ltd.

The company has gradually developed from producing and processing only two approved varieties of Dannanxing and Jianqu into a modern Chinese medicine decoction piece production enterprise dominated by fermented Chinese medicine, toxic decoction pieces, small packaging Chinese medicine decoction pieces, and direct administration decoction pieces.

The company has always adhered to the ancient motto of "although no one sees it, heaven knows what is in mind" and the belief that "health is related to national economy and people's livelihood". Led by representative inheritors of intangible cultural heritage, the company deeply inherits and innovates traditional crafts, among which the natural fermentation and processing techniques of Dannanxing have been listed as intangible cultural heritage of Deyang City.
