I have been playing violin for 20 years since the age of 5.  I started with a conservatory teacher in Beijing from the Chinese Central Music Conservatory .  Later in Canada, I studied with David Zafer.  I used to be a member of Columbia University Orchestra which give performance at the end of every semester.

If you're interested in collaborating in chamber music, I'm looking for piano trios or string quartets.
