First of all, the leading school in Hangzhou is an independent complete middle school, usually with multiple grades and classes, while the branch school is a teaching place set up according to the students' residence and educational needs. Because of the small scale of the branch school, the teaching content is relatively simple.
Secondly, the educational contents of the two schools may be different, mainly because leading schools will formulate different teaching plans according to students' specialties and abilities when enrolling students, while branch schools need to adapt to the teaching plans of leading schools.
In addition, the leading schools in Hangzhou are usually ordinary high schools, while the teaching types of branch schools are more flexible, and there may be different types of schools such as junior high schools, high schools or training courses.
Finally, the management methods of the two are also different. Leading schools in Hangzhou usually have a complete administrative organization and management system, while the education management of branch schools is more supervised by sending staff from the management system of leading schools.
In a word, although the leading schools and branch schools in Hangzhou belong to the same school, they are different in scale, educational content, type and management.
