Ps: I have been writing a paper for my wife recently (entrusted to me with full authority), and I have recently entered the final stage of format adjustment. Because I didn't even automatically generate the catalog when I was in college (I didn't know what Baidu was at that time), I made various Baidu, Google and guesses on the way to format adjustment.
If you have any questions, please tell me, hoping to help friends in need.
