Our Chinese sister site iolc.org.cn pushed its spring update last week. The archive now covers:
- IOL 2003-2025. All twenty-two editions, individual and team round, with Chinese-language walkthroughs for the harder problems.
- NACLO 2007-2025. Round 1 and Round 2, with solution sketches in Chinese.
- UKLO Advanced 2015-2025. Selected problems with Chinese annotations.
- Editorial articles. Around forty long-form Chinese essays on individual problem types and historical context.
If your first language is Chinese, the iolc.org.cn archive is often more efficient than working through English-only solutions. Many of our mentors started there. The two sites share resources upstream but maintain independent posting cadences.
If you would like a problem walkthrough translated either way (Chinese to English or English to Chinese), WhatsApp us with the problem and target language. We are not a translation service, but we will route requests to whichever mentor pool can help.
