Since the ancient books you mentioned can be downloaded from the Internet, the title and author should be known. According to these clues, I suggest you go to various libraries and large bookstores in your city to find physical books. Then copy the page number and other details, and look up some words at the same time, because there are many mistakes on the internet.

As for whether you show them the source of the reference, it depends on the strictness of your school teachers and the reading range of the peer reviewers. If he happens to have read one of the books you listed, it's easy to see the flaw. If you have time, I suggest you don't be opportunistic. I believe you are a serious student.

Although time is tight, this kind of meticulous work still needs to be done, and it cannot be sloppy. You can ask your classmates, teachers or friends in other cities for help. What city are you in? Isn't there a big bookstore or other university library?
