Personally, I think ancient Chinese is much easier to write. Because there are too many unknown topics, it is easy to study the results. The difficulty lies in consulting a large number of ancient documents. Ancient literature also has many branches: phonology, exegetics and so on. Of course, this is for students who really want to spend their time writing.

Modern Chinese has been learned a lot, and it is easier to copy it, but modern Chinese is not a true Chinese inheritance after all. Too boring

Both ancient literature and folk literature should study hard, and folk culture may really go to the local countryside. It's troublesome, and it doesn't necessarily have a result.

Chinese teaching theory shows that you are from normal university. These theories are all good, but the requirement of the paper is innovation, and platitudes are definitely not good papers.

Compared with China literature, foreign literature is better to read foreign original works. Ha ha.

The above is my personal analysis of several aspects. I wonder if you are satisfied with this answer?
