Beijing Tong Ren Tang is a well-known time-honored brand in traditional Chinese medicine. It was founded in 1669 and has a history of 337 years. Tong Ren Tang began to "undertake official medicine" from 1723 to 1911. For 188 years, Tong Ren Tang followed the royal standards for selecting medicinal materials, adhered to the palace secret recipes and pharmaceutical methods, and formed a strict quality supervision system. The organic integration and influence between Tong Ren Tang and the Imperial Hospital and the Imperial Pharmacy of the Qing Palace formed the special style and traditional knowledge of Tong Ren Tang's traditional Chinese medicine. Tongrentang's TCM culture is embodied in the values of "cultivating benevolence and virtue, saving the world and maintaining health", the quality concept of "no labor is spared even if the processing is complicated, no material is reduced even if the taste is expensive", the business philosophy of "honesty and loyalty, and harmony among people", the professional ethics of "honesty and fairness, and equal treatment", as well as Tongrentang's brand and unique marks, "Le's Generational Inherited Pills, Powders, Pastes and Pills" and "Tongrentang Qianxiu Various Symptom Pills, Powders, Pastes and Pills General Catalogue", Tongrentang's traditional TCM processing technology, and Tongrentang's pharmaceutical characteristics, which is the integration of traditional TCM and palace pharmaceuticals, can be summarized as "unique prescriptions, superior materials, exquisite craftsmanship, and significant efficacy". However, under the influence of Western modernization, Tongrentang's original traditional TCM processing technology and pharmaceutical characteristics are facing the dilemma of survival and development, traditional pharmaceutical methods are constrained, and unique technologies are facing the risk of loss. Tongrentang is making unremitting efforts to protect this excellent traditional culture, and it is urgently needed to be respected and protected by the whole society.
