Yangshengtang and Tongrentang are both domestic brands. In contrast, Tongrentang is stronger because it is a century-old brand. Shiseido is a Japanese brand, which can't be compared with domestic brands, and its products are not in the same category. Yangshengtang is an enterprise that produces health care products. Tongrentang mainly produces Chinese patent medicines and health products, while Shiseido in Japan only produces cosmetics. Good luck!
