I went to a water puppet show, one of Vietnam's national dramas. The detail design and manipulation of the puppet itself are far beyond my medical treatment. But the beauty of dancing is far worse than the impression series of "color sheets". The audience is mostly foreigners. The water puppet is a quintessential form of art to deduce scenes of Vietnamese daily life and some national myths. It is indeed a good means to disseminate Vietnamese culture. However, the translation of the content needs to be further strengthened. Otherwise, the freshness will disappear, and the performance of an hour without understanding will be slightly lengthy. The ticket price of 100,000 Yuedong is really the price of conscience (30 soft sisters). How to promote the public welfare of culture (science popularization) in some domestic operas? It is in accordance with the law that people who are not interested in it have to spend money and time on it.
