Last term, I hosted an exchange student calling Jacob from the Great Britain to our school. He really cared for Chinese Culture. Jacob asked me to show himself around our city on weekends. So I took him to many local place of interest and we also go to the theater to watch a show of Peking Opera. He was very fond of the performance that he decided to learn it. My father happened to know a master of Peking Opera and introduced Jacob to him. Jacob was great honored to be one of his students. Put his heart into it, Jacob made a rapid progress. When he returned England, he gave a performance in his school, it helped him win much admiration from his classmates.
