Most of them come from schools. After all, publications-related organizations are approved by the Propaganda Department of the Party Committee of the school, so they are generally affiliated with the Youth League Committee or organizations of the school!

However, it can also be sponsored by foreign enterprises and institutions in the school. For example, let them sponsor your publishing expenses, and you can give them some advertisements for free!

Part of it should come from membership fees!

There is no other good way!
