Decide what type of book to write. Content will play an important part in whether or not you're published in China. Chinese law requires publishing businesses to "adhere to the guidance of Marxism, Leninism, Mao Zedong Thought and Deng Xiaoping Theory."
Find a government-licensed publisher interested in your book. China does not encourage individuals to self-publish books. In order to self-publish, you'd need to set up your own publishing "unit," something difficult for a non-Chinese citizen to do.
Revise the book depending on editorial and political concerns. The publishing house may not want to submit the manuscript to government censors until all possible damaging material is removed. Revisions may be extensive.
Get approval from the General Administration for Press and Publication so that the book can be printed.
Find a licensed publishing unit to distribute the books.
