When talking about the career of being a teacher, a lot of people will speak highly of it, because this career enjoys a good reputation, and the most important thing is having rich extra income. Many teachers gain their income by giving students extracurricular tutoring, which can earn much more than their salary. The news reported that Chinese tutoring market has great potential, because the parents are willing to pay more money on their children’s education. It seems that being a teacher means earning money easily. Actually, a lot of teachers are tired on their work as they need to supervise the students, so even on holiday, most of them choose to take a break and refuse to do the tutoring work. We are easy to be misled by the untrue news, and sometimes even misunderstand the career.
