Traveling to Fujian, this stop came to Xiamen and went to Gulangyu to play. Passing by, I saw this piece of Zaiyu Museum. This is the traditional Chinese medicine produced by Zhangzhou Pharmaceutical Co., Ltd. The secret recipe originated from the Ming Dynasty court and has a history of nearly 100 years. I saw a museum of it here in Gulangyu Island, and the museum introduced the history, efficacy and so on of this Chinese medicine, and promoted the film to tourists in pictures and movies.
