I think we should just set a range, not too big a topic, or it will be difficult to write, but it should not be too small. In short, we just think we can adapt, that is, how much content do you want to write, and then we'd better check the information to see if anyone has written it? There is also a saying that how much people have written and how much can they write? In short, it is necessary to write so much on this topic.
