You need to mark it, but you don't need to change the font and start a new line, just use double quotation marks, then mark ① at the bottom of the current page and indicate the source, and mark it again ... If you don't directly quote the original text but summarize it yourself but it is relevant, write it in the reference. My graduation thesis is still being criticized ~ ~ (> _ <; ) ~ ~ ~, good luck.

If it is the same WORD page number, it should be marked in the order of ①, ② and ③. If the same page is quoted from a book, just write the same as above after the serial number, and mark it clearly. You can go to China HowNet or VIP to write a few master's and doctoral theses to see the format. If necessary, I can send you two references.
