Before going to China, Mr. Black was a doctor in America. He worked at a hospital in New York. He got up early and went to work by car. The hospital was far from his house. He had his lunch in the dining hall of the hospital. He was very busy during the daytime (白天). In the evening, Mr. Black watched football matches and learned Chinese. He went to China in 2015, and he began to fall in love with (爱上) Chinese people and Chinese food. Now his Chinese is very good. He is a teacher in a big school.
