The benefits of publishing houses are related to the types of books published, and university textbooks and dictionaries are better.
At present, most publishing houses are still public institutions, but the reform of publishing houses has begun, and many provinces have established publishing groups, which are no longer public institutions. Even if you enter a publishing house that has not been restructured now, it is probably not compiled, which is the same as the employment system.
The most important difference is that institutions are well paid and have stable jobs.
