Misc

My name "蒹葭"" originally comes from one of the oldest poems in China, Classic of Poetry《诗经》. "蒹葭" means "reed". And yes, my name bothered me a lot when I was young. My English name is Suzy, which in Chinese is written as "苏茜". Try to find something in common between the two names.
I play Pipa, a traditional Chinese instrument. I'm a member of Hopkins East Asian Traditional (HEAT) Ensemble. Check out our Youtube and Instagram.
I recently got a camera and am learning to take pictures and editing with Lightroom. Click if you think I'm a photographer.
