Where can I find a guitar teacher in Shenzhen?

Shenzhen University in Nanshan District has a Sendi musical instrument store. They mainly sell guitars and band's peripheral products. You can find many famous foreign pianos here, and the price is also very low. Our band are all looking for guys here. There is a guitar teacher named Xie, who is very awesome. Many musicians in our school are going to learn piano from him in the summer vacation and improve themselves crazily.
