Why didn't Feixi County take the joint entrance examination of public institutions?

It's a separate recruitment. According to the People's Government of Feixi County, official website, institutions do not participate in the joint entrance examination of institutions, and implement hierarchical management. Governments at or above the county level have the autonomy to enroll students separately. The examination of public institutions usually refers to the examination compiled by public institutions, while the joint examination of public institutions refers to the form of joint examination of public institutions conducted in several provinces or prefecture-level cities in the same province at the same time, with the same content and the same scoring standard.
