Primary and secondary schools are different from technical secondary schools, vocational schools and universities.
If you want to be a teacher in public primary and secondary schools, you really have to go to normal university, because public primary and secondary schools only recruit graduates from such schools.
However, if you want to teach in a secondary school, vocational school or university, you are not restricted. You just need to meet the recruitment requirements of the school. You have the opportunity to graduate with a master's degree or a doctorate.
In addition, do you expect to be a teacher to have a stable income and enough holidays, or do you really want to educate others?
Now there are many educational resources and developed channels and technologies. If you have mastered a certain skill, you can start classes online, such as Thousand Chats, Litchi, Himalayan FM and Zhihu Live Broadcasting. As long as the course is good, you can receive a lot of money and build your own brand.
If you master a skill, you can also go to an educational institution to teach students. There are early education institutions, English remedial classes, Chinese extracurricular remedial classes and other schools.
Some trainers specialize in giving classes to employees of enterprises, which can not only make a lot of money, but also communicate with employees of enterprises, understand various industries and broaden their horizons. I know a friend who is the mother of triplets. After learning yoga by herself, she mastered it very firmly, so she went to a yoga class and became a part-time teacher. It can not only exercise, strengthen the body, but also win the love of students, which is also a way to be a teacher. So I think the motivation of modern people to continue learning is very sufficient. As long as you have the strength, there are many opportunities for you to become a teacher.
