Ask a question about spelling in history books.

You can see which version of Hanshu published by Zhejiang Ancient Books Publishing House is reprinted, thinking that there are many ancient books with different stereotypes in historical inheritance. Now there are many versions of a book, and the printing technology is unified, but different books are derived from different versions of history, so we can pay attention to it. Now our most common version should be the version of Sikuquanshu published by China Ancient Books Publishing House in Qing Dynasty. Different versions will have what you said, but we should also pay attention to whether all the places where Chao Cuo appears in the book are printed as Chao Cuo. If this is definitely based on different versions.
