However,you could be wrong. Kang Jian is a 17-year-old student from Shanghai. Last year he went to visit his aunt and uncle in SanFrancisco.He found it interesting that so many products in the local shops were made in China.“I wanted to buy a toy car for my cousin,but even though most of the toys had American brands,they were made in China.”Toys are not the only things made in China."I wanted to buy a pair of basketball shoes,"he explains."But I had to visit five or six stores before finding a pair made in American!"He realized that American can hardly avoid buying products made in China."In fact,"he continues,“there were so many things made in China-footballs,handbags,pet food,mobile phones. Even American flags are made in China!"Kang Jian thinks it's great that China is so good at making these everyday things. However,he wishes that in the future China will also get better at making high-technology products that people can buy in all parts of the world.
