Note: This blog is just a joke :)

Hi, Codeforces. I recently found out some interesting things about the famous Russian coder 300iq. I realized that he had a strong relationship between Chinese people while himself was a Russian. Some proof here:

Proof 1 During the recent contest Helvetic Coding Contest 2019 online mirror, 300iq joined the competition with two other users. Interestingly, the other two users in the team are both Chinese IOI team members.

Proof 2 In a recent blog sent by me, I was requesting Chinese OI statements. I was expected to see a Chinese, but 300iq was the first man replied.

Proof 3 Everyone knows the 300iq contest in gym. Among the 5 testers of the contest, 4 are Chinese.

Proof 4 300iq reviewed many Chinese rounds. (For example, recently the round #564 and #573) (But of course he reviewed many Russian rounds as well)

UPD

Some ideas from comments(In fact, I don't know which are true, which are false,plz judge it by yourself :P) :
