A lot.

No matter which e-commerce platform you shop on, if you want to buy health products online to condition your body, and you still believe in old brands, you will find an overwhelming number of "Tongrentang" OEM products, Beijing Tongrentang--the suffix "used in the inner court" ", Nanjing Tongrentang, with the suffixes of Green Gold Home, Lejia Old Shop, Liuhe Qiankun, Chinese Medical Center, and Tianjin Tongrentang Sun Brand. These are three Tongrentangs, don't be confused. 1. Establishment: In the beginning, Tongrentang did not have any brand, it was just a medicine name or a business name. The founder was Le Xianyang. In 1669, Le Xianyang, who ended four generations of practicing medicine, took the "Book of Changes" "Treat everyone equally regardless of whether they are close or distant." "Tong Ren Tang" is the name of Tong Ren Tang Pharmacy, which is equivalent to the establishment of the "Tong Ren Tang" brand name in the imperial city of Beijing.

2. Split: Beijing and Nanjing Tongrentang: In 1926, Tongrentang's business was booming. Le Duzhou, a descendant of the Le family, was ordered to open a Nanjing branch of Beijing Tongrentang to expand its business territory. At that time, Nanjing Branch's capital, drug formula and technology were consistent with Beijing Tongrentang. After the public-private partnership in 1956, both North and South Tongrentang implemented corporate legal person management, so Beijing Tongrentang and Nanjing Tongrentang emerged. Beijing Tongrentang has registered the "Tongrentang" trademark, while Nanjing Tongrentang is just a well-known time-honored commercial brand without the Tongrentang trademark, and has registered trademarks such as Lejia Laopu.
