There are many such products made in Hong Kong. Like Huang Daoyi, Yimata, etc., including the brand you mentioned, which is produced by Hongwei Company. Not to mention that the effects of these products made in Hong Kong are really good, this is due to the war and the Cultural Revolution in the early years. Many Chinese medicine practitioners fled to Hong Kong, taking all the good prescriptions with them. There are many traditional Chinese medicine products in Hong Kong now, which are really good. Worth believing. I can introduce you to a purchasing agent platform for this type of Hong Kong goods. You can refer to it on Baidu or Google: iGo Hong Kong.
