The publishing house is a traditional publishing unit that mainly publishes books, while the periodical press is a publishing unit that mainly publishes periodicals. Publishing houses generally publish books, and periodical clubs generally publish periodicals, both of which are important parts of publishing units in China. However, there are also non-independent periodical editorial departments in publishing units in China. Non-independent periodical editorial department is a publishing unit affiliated to a legal person, which can be a publishing house, because there are often legal person units that publish periodicals without setting up periodical clubs, but only setting up periodical editorial departments as their subordinate departments. In other words, the periodical editorial department under the publishing house can also publish periodicals, and it can also be regarded as a publishing unit according to the Regulations on the Administration of Publishing.
