The story
In 1669, the eighth year of the reign of the Kangxi Emperor in the Qing dynasty (1644–1911), Tong Ren Tang was established in Beijing by Yue Xianyang who served as a senior physician at the Qing imperial court. In 1702, the company relocated from Beijing to the address from which it has operated ever since. In 1723, Tong Ren Tang was appointed the sole supplier of herbal medicines to the imperial court by the Yongzheng Emperor and remained in that position until the collapse of the Qing dynasty in 1911. In 1924, the company Tiger Bone Wine was awarded at the Leipzig Trade Fair, making the product the most popular type in commerce.
