Keep your job at school. On-the-job schooling refers to the behavior of going to school when the unit retains its post. Going to school is a customized knowledge learning process for the educated, which generally includes primary schools, junior high schools, senior high schools and universities. On the other hand, modern education provides kindergartens for preschool children. Primary school to junior high school is nine-year compulsory education, and the government has the obligation to undertake children from all over the country to go to school, while high schools, universities and even kindergartens learn by themselves.
