My high school art teacher, Kong Liang, taught it to us in our second year of high school. The person is very funny and the painting is also very good. Unfortunately, I am in a science class and do not follow the literary route. I spent the whole week of class bragging and watching movies, and I did not learn any real skills. It is a pity. However, many of the art candidates in our school (No. 1 Middle School) were taught by him and their scores were very good. He is a great person and he studied under famous masters. Let me tell you a little secret, his wife is my English teacher, she is very nice and enthusiastic.
