It is now listed as a "level secret technology" by the state. The place of inheritance is Xinjiang County. According to the "Xinjiang County Chronicles", there were 34 Chinese medicine shops (stores) in Xinjiang County at the end of the Qing Dynasty and the beginning of the Republic of China, all of which mainly sold Chinese patent medicine pills, powders, pastes and pills. At that time, the "Dianshe Pills" produced by Deyitang, the predecessor of Shuangren Pharmaceutical, had long been sold in Shanxi, Shaanxi, Hebei and Henan. "Dianshe Pills" was originally a secret medicine used exclusively by the royal family in the Qing Dynasty palace, and was later spread among the people by the eunuch surnamed Wang. Hebei Hao got this secret recipe and built Deyitang Chinese Medicine Shop in Xinjiang County. Because of its outstanding efficacy, its reputation rose rapidly. Deyitang was well managed and became the largest Chinese medicine shop in Xinjiang County after liberation. During the public-private partnership, Xinjiang Chinese Medicine Factory was established on the basis of Deyitang. The traditional Chinese medicine for treating surgical diseases, Dianshe Pills, has become one of the factory's flagship products. With its long history and unique efficacy, it is marketed at home and abroad and was listed as a "secret technology" by the state in 2005. In 2010, the "Shuangren" brand of Dianshe Pills was named a famous trademark in Shanxi Province.
