Why do so many people want to apply for junior high schools when it comes to teacher preparation?

First, the salary of junior high school teachers is higher than that of primary school teachers, so it is normal that more people take the exam. Second, the competition for junior high school teachers is relatively low, because after all, there is still a certain threshold, and the requirements for junior high school teachers are not as high as those for high school teachers, so there are more people applying for the exam.
