Amateur Radio

I obtained my amateur radio operation licence from CRAC in 2024. Now I have a callsign BI1TUD. View qrz.com for more information.

Competitive Programming

I used to be an active participant in competitive programming (CP). I have won multiple prizes in CP competitions, including International Collegiate Programming Contest (ICPC), China Collegiate Programming Contest (CCPC), National Olympiad in Informatics in Provinces (NOIP).

You can find me on Codeforces, Atcoder.

Also, I’m deeply involved in CP community building. I have made contributions to multiple CP communities, including Luogu Online Judge and OI Wiki.
