Since I have participated a lot of mathematics competitions during the high school, I am interested to pursue more about pure mathematics. Click here to find my list of all classes, some lecture note, research, and college mathematics competitions!

I was a silver medalist from International Mathematical Olympiad 2014, 2015, and 2016. Because now I do not have a chance to participate the competition again, I would like to share some interesting problems and techniques I often used during the competition.
