The best anonymous answer, 99% probability comes from Overseas Chinese Publishing House itself. I personally experienced the answer and bought copies of Common Sense of Chinese Studies, Classic of Chinese Studies and Water Margin 120 (I and II) by China Overseas Chinese Publishing House. It is easy to misunderstand typos and wrong numbers and years. There are also logical errors that can be seen from the context without looking up the information, which shows that the release verification is completely unintentional. As far as I am concerned, there are more than 20 mistakes in these books. There is no professionalism and responsibility that a big publishing house should have, and money is not earned like this. Here are also some good publishing houses: People's Literature Publishing House, Zhonghua Book Company, Shanghai Ancient Books Publishing House, Zhejiang Ancient Books Publishing House, Qilu Bookstore, etc.
