This maybe off topic but i really want to know how are chinese coders that good. Among them jiangly can be considered as exceptional. I mean he is very much consistent in getting single digit ranks in recent contests and the number of Wrong Answers he gets on problems is very very low compared to others. How is he that good? I have watched many of his streams and the way he gets the main idea of solving complex problems so fast is truly fascinating. Do they practice problems from any chinese website to get that much good? If any one knows please do share. I could not find much details about jiangly anywhere. His mind is a mystery.
