Because the salary levels of different regions and schools are different, the salary of private schools will be different, so I can't answer your question accurately. Generally speaking, the salary of master graduates who are engaged in junior high school history teachers in first-tier cities in private schools is roughly between 4000 yuan-15000 yuan. The specific salary level depends on the size, popularity, geographical location, work experience, background and other factors of the school you apply for. If there are specific schools or regions that need to know, you can consult the relevant schools or local education administrative departments for more detailed and accurate information.
