This website has a paper channel of "news archives", and under it, there are many columns of archives papers. You can check it yourself. These columns published influential papers published in authoritative academic journals in China. After reading these papers, I believe your theoretical level will be improved a lot. Good luck.
You can go to Baidu or Google and search for "cssci Academic paper net", which ranks first.
The reason why the website does not link is mainly to avoid the suspicion of "trust".
Because it is really good, it is highly recommended.
