Teachers are also teachers, teachers, mentors, etc. This is a profession since ancient times. It is a person who teaches knowledge to students. There are various types of education (such as Chinese, mathematics, etc.). ), and the class teacher is also one of the teachers. It also refers to people who are worth learning in some way and can bring you some correct knowledge and guidance. The related festival is "Teacher's Day".

In ancient times, teachers were often called "masters, masters, teachers, lecturers, etc." Professions similar to teachers include lecturer, coach, professor, teacher, doctor and so on.

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.
