I bought it after seeing the advertisement, because it was made by Wei Liu and another old actor who I think is virtuous and artistic. I think it is more credible. I always have intestinal discomfort, dull pain and take a lot of medicine. I bought it on August 26th. I felt very comfortable after drinking a cup in the afternoon, but it didn't hurt at night. I don't know what to say, but it's amazing. In fact, I have always used it with the mentality of counterfeiting. 198 yuan is not expensive here, but it's just an ordinary cup. I'm going to keep using it and see if it can be as magical as advertised in a week.
