Primary schools in some places also accept teachers from pre-school education colleges. You can be a primary school teacher if you have a primary school teacher qualification certificate. The subject you choose to teach depends on the teaching major of your primary school teacher qualification certificate. As long as there are schools that have been admitted, they can teach primary schools. If you just graduated from preschool education and don't meet the employment conditions of primary school teachers, you can also be a substitute teacher in some places, but there is no preparation, the salary is relatively low, and you have to change schools every year. If you attend a public primary school as a substitute, if you are excellent, you may be recommended as a teacher, but this is rare.
