Advantages and disadvantages of the integration of primary and secondary education are as follows. The advantage is that the merger of schools is conducive to the rational allocation of educational resources, so that more students can enjoy better teacher resources. In a sense, it has reduced the government's investment in education. The disadvantage is that the allocation of teachers is reduced, and many teachers are facing survival problems. If schools are merged blindly and unplanned, students in a single school may be overcrowded and the teaching quality may be reduced.
