In Codeforces Round 602 (Div. 1, based on Technocup 2020 Elimination Round 3), djq_cpp, aged 14, smashed the world record of the youngest Legendary Grandmaster with a rating of 3055!

Jiangqi Dai is undoubtedly the best OIer(i.e. competitive programmer) in junior middle school all over China(perhaps the world). He is likely to get a perfect score in CSP2019-S2, the first round of the selection of IOI participants in China. Also, he has got gold medals in APIO and the Winter Camp(rank 12).

It is widely believed that his age is the only obstruction keeping him from an IOI gold medal, because of China's policy.
