In the dialogue of the novel, some words are in quotation marks, and some are not in quotation marks. Use "Shuo, Dao" instead of quotation marks. What is the difference between these two methods?

If there are quotation marks after what is said, it is usually an ongoing conversation. And if it is said, the way of using Tao without commas is to simply pass it by. There is no ongoing dialogue, just what the person said. What should be described next is the reaction of other people or jump directly to the next scene. The use of these methods in the article means that we don’t want to reuse the same symbols too much, so as not to be boring.
