Bridge:

I once was very good at Bridge.

10 years ago I was high school champion in Beijing

In 2012 I played in the YACBL U19 tournament. in Philadelphia, PA.

I no longer play now because I have no time to practice at professional level.

​

Astronomy:

I was the 9th president of USTC amateur astronomy association, and had to answer some stupid interviews.
