Another Look
I like jogging, swimming, sports, reading, cooking (on the way :-）), …
I learned guitar, Chinese calligraphy, pencil sketch, basketball (point guard for starting lineup, part of small forward) when I was a child/teenager.
During my studying journey, I spent wonderful time in Beijing, Jinan, Qingdao, Rizhao, Shenyang, Shenzhen, Aichi, and Singapore.
