Spanish visa for russian, who study in China

Hello, dear!
Please, would u help me?
I'm russian girl, study chinese at Xiamen University ( Fujian province).
This october i will go Spain ( tourism). I already have spanish visa (type C, multy, from 30.10.11 until 25.04.12) it was issued in Russia, Moscow. I was staying there 2 weeks ( at november of 2011).
Now i have no opportunity to go Russia to get visa and i need apply for spanish visa here.
Is it possible? If yes, where should i send my documents ( or must i submit an application in person) - Shanghai or Beijing ( or maybe Guangzhou). And where can i get a list of nesessary documents. I don't know the procedure of submitting an application here, in China. Excuse me for disturbing you, please.
Thank you so much.
Best regards.
Liliya.
