Hello, dear visitors!

My name is Yaling Chen (陈亚玲), and I am a chemistry teacher at Shenzhen Middle School in Guangdong, China. I have been coaching students for chemistry Olympiads for more than 13 years. Over the years, dozens of my students have earned Gold Awards in China ChO, and one of them went on to win a Gold at IChO.

Now with the help of AI, studying Chemistry Olympiad materials from any country and in any language is easier than ever. I hope this site can serve chemistry enthusiasts, Olympiad participants, and friends from around the world.

Have fun!
