I'm afraid my answer is hard to convince and satisfy, but let's talk about my opinion. As far as ancient literature is concerned, which school is better, China Ocean University or Shanghai Normal University? First of all, I want to say that Shanghai Normal University should be better. The reason is that for Shanghai Normal University, the major of ancient literature is their housekeeping major. If this fails, the school will be completely finished. For China Ocean University, the major of ancient literature is only an affiliated major, and their way of eating is not available in the marine major. This situation is the same as many engineering schools that offer Chinese language and literature majors. Secondly, I want to say that choosing a school depends not only on the overall situation of the school, but also on the personal situation of the tutor. Sometimes the school you choose is not very strong, but the tutor is very strong and has a good reputation in the industry. Thirdly, I also want to say that when choosing a school, we don't need to worry too much about which school is stronger, because there are many other factors to consider when choosing a school, such as the location of the school, whether it can be admitted, whether the questions of this school are suitable for our own exams, and how the employment prospects of this school will be after graduation. These are all worth considering. As for the differences between Yuan Xingpei's History of China Literature 1999 edition, 2000 edition and 2005 edition, I can't say clearly in a few words. In fact, ordinary books, with different versions, are all minor revisions, and there will be no earth-shaking changes, so you can rest assured. The most reliable way to know the difference between them is to find out all three books, compare them and make them clear.
