A number of Chinese universities have held four job fairs in Toronto, New York, Boston and San Francisco  A survey of questionnaires conducted by Chinese students attending the job fairs shows that 67% of them want to return home to work, and 33% will seriously consider the option of returning home

 It can be seen that working in the United States has lost its attraction to foreign students, and it has become a common practice for people to want to return home
