Although we usually call teachers in schools "teachers", the "teachers" here are actually teachers' jobs, and teaching is their basic function. Since the Ming and Qing Dynasties, teachers have generally been called "Mr.".

Until the end of 19, He Ziyuan, the founder of modern education in China and a veteran of the Revolution of 1911, introduced western learning (American education) to China, and after establishing a new school, they began to define teachers as "teachers" in the student code of conduct. However, most students habitually change the title of "Mr." to "teacher", which started from the era of the National Government and has been in use ever since.

In 20 16, the number of full-time teachers in various schools at all levels in China was157.82 million, including 5.789 million full-time teachers in ordinary primary schools, 3.488 million full-time teachers in junior high schools, 2.232 million full-time teachers in kindergartens, 53,000 full-time teachers in special education and 65,438 full-time teachers in ordinary high schools.
