As we know, Educational Codeforces Round 122 will be held on the evening of Jan. 31, which is also known as Chuxi in China.

It's the time for Chinese to get together with family but not with computers. So I don't think it's a good time for Chinese to take part in.

Also, I wish we Chinese could have a good time with family tomorrow night. And don't 卷! >_<

It is only a suggestion, I just want to share my opinion.
