The founder, Le Xianyang, was originally a wandering doctor. He respected the creed of "keeping in good health and saving the world, but medicine is the most important thing", took practicing medicine and selling medicine as the cause of keeping in good health and saving the world, and founded Tongrentang Pharmacy. He said: "Colleague, the word can be called Tang. I like its fairness and elegance, so I need to be ambitious." According to the survey, the word "colleague" originated from the Book of Changes, which means that no matter far or near, they are treated equally.
