The day before yesterday, the child and his wife went out together. The child still had a cough after catching a cold a few days ago, and the cough was aggravated by too much running in physical education classes at school. When I was driving through Yangjiang, I happened to get off for a break and saw a local specialty “Chuanbei Huangpi”, so I bought it and tried it out, and it worked. Sometimes I think about the fact that medicine and food are the treasures of our ancestors, so we nutritionists should combine food and Chinese medicine to benefit more people.
