What are ancient Chinese sentence breaks like in modern times?

There was no complete punctuation system in ancient times, so there were no punctuation marks in ancient Chinese. The so-called "reading sentences" means breaking sentences, which requires teachers to teach and analyze themselves.

Because reading ancient Chinese without sentences brings a lot of trouble to reading, after the implementation of modern punctuation, some ancient book publishing units, under the guidance of relevant state departments, organized manpower to gradually add punctuation to ancient Chinese.

Because some ancient books are published by more than two publishing units, it also causes the problem of "version" of broken sentences.
