It can be published in Hong Kong for a fee.
You can contribute directly to the publishing house in Hong Kong, or you can publish your works through the publishing company.
The cost generally ranges from several thousand yuan to 20 thousand yuan, depending on the specific information of your work and how many copies you want to print.
Please note that not all Hong Kong publishers accept paid publishing. Most of the Hong Kong publishing houses that can be published by paying fees are those registered by mainlanders in Hong Kong. In Hong Kong, registering a publishing house is no different from setting up a general company, and anyone can set up it. In addition, the books published by Hong Kong Publishing House are not completely unable to be distributed in the Mainland, but only through certain procedures to introduce publications into the Mainland. Of course, it is time-consuming, laborious and unnecessary for individuals to introduce books published in Hong Kong.
At present, the domestic publishing policy is gradually relaxed. If it is not necessary to publish it from Hong Kong, it is recommended to publish it in a mainland publishing house to avoid many subsequent troubles.
I hope it will be helpful to you and I hope it will be adopted.
