Today I opened Luogu for the first time.

• On Luogu, if you practice with *3000 rated Codeforces problems, you are not an International Grandmaster, you are "NOI-" ("National Olympiad in Informatics minus"?). So the average Chinese IGM knows he is not so competitive at the national level (skill issue) and he must tryhard to reach "NOI", "NOI+" and "CTSC" level.
• There are a lot of editorials written by contestants (about $$$10$$$ for each problem), which can be better than the official editorial. This holds for both easy and hard problems. Learning from Luogu editorials seems fun!
• The community is not toxic at all! If the tests in a problem are weak, according to Luogu users the reason is not "the author is retarded", but "the author is still too young" (i.e., $$$11$$$ years old).

If you wish to become LGM, of course the first step is creating an account on Luogu.
