His ancestors practiced medicine for three generations. Since he was a young boy, he read widely from prescription books, and devoted himself to the research and production of prescription medicines. The pills he makes are all made of pure and authentic materials, and the production is fine and rigorous, and the patients have remarkable results after using them.

He took the practice of medicine as a kind of health care to help the world effectiveness in the community's highest pursuit of business, he said: "can be health, can help the world, but medicine for the most." Le Xianyang founded the Tongrentang Pharmacy in 1669, the eighth year of the Kangxi period of the Qing Dynasty.

Most of Tongrentang's more than 400 proprietary Chinese medicine formulas have been tested many times, with rational formulas, proper dosages and high efficacy.
