Hi Xinyan,
Welcome to Zurich!
I am interested in Chinese culture and actually go to China for the 2nd time next month!
I would love to learn some Mandarin, I fighting German at the moment so have not been able to look into this much.
One thing I am into learning is Chinese cooking.
Zurich is a great place for sports, you will see plenty of Yoga and fitness/dance places about, swimming is around as well with the lake always as an option

Hiking is also great, I can't wait for summer to go exploring myself!
PM me to discuss if you would like some to me and maybe I can help with your English and you can teach me a few useful words for my trip.
Chris
