Where to buy a good quality violin in Beijing?

Hi,
I'm planning to have a holiday for about 10 days, and will be booking a hotel somewhere in the city close to Tianmen Sq. I just wonder if you can give me a couple of recommendations regarding getting a violin of reasonably quality in Beijing. Also, where are the best places to get some music books/sheet music?
Thank you very much for your help.
Kind regards,
