If you are not Chinese or you are not interested just don't read this blog and leave no vote, thank you.
If you are a Luogu user, please don't post useless "qpzc"(*) comments under the MX contest announcement, in CodeForces the comments are not displayed in time order, making that action useless.
Here, your contribution is important, when a stranger wants to know you he will check your contribution. If you keep posting confusing comments, it will significantly decrease, and one day all CodeForces users will think that most Luogu users are nerds. The Luogu Moderators downvote every "qpzc" comment in CodeForces.
Spamming meaningless comments is not good for the CodeForces community.
*: qpzc = 前排支持 in Chinese = be the first ones to support a new topic ~ basically meaningless in CodeForces
