He Wei is a 13-year-old student from No. 1 junior high school of Changsha. Last month, he went to New York to visit his aunt and uncle. He wanted to buy a toy robot for his little cousin, (1)but he found it interesting that so many products in the local shops were made in China. Though many toys were American brands, they were made in China. In fact, toys are not the only things made in China. He wanted to buy a pair of basketball shoes, but he had to visit five or six shops before finding a pair made in America. So in America, people can hardly avoid buying products made in China, because China is good at making everyday things, such as football, handbags, pet food, mobile phones and so on.
