Many new graduates decide to start their careers as a teacher in China in order to make money to pay off student loans. Some of the ex-pats end up teaching in China because of their interest in Asian culture.
No matter what kind of intention you may have, teaching in China is meaningful for your career and even entire life, not only for financial reasons. International experience, personal experience, and global experience are all valuable. Many people have advanced their careers by learning Chinese, meeting contacts worldwide, and serving as an essential connection as our globalized world is developing.
