Beijing Opera is one of the most important Chinese cultural heritages. I spent the who class to introduce the origin of opera mask and the classical stories to my students. We talked about the difference between Eastern and Western masks. What’s more, I showed a folk art video, how quickly the performers switch the masks. They were totally surprised by watching it. Even some of them want to try to learn that magic. Some of my students really enjoyed wearing masks and customs and playing an important role in the stories of popular opera. For example, being the hero, Yu Guan, who is the one of the bravest general in the Three Kingdoms. In addition to, I taught some new words to my students, like how to say red in Chinese and what the specific meaning of each color in the Beijing Opera.
