Where is Xi 'an Photography Equipment City?

Haha, K5( 18- 135) just bought before the National Day. One card \ bag \ battery \UV mirror \ tripod \ invoice totals 12500 yuan. There is a large photographic equipment city in Dongxin Science and Trade, Lujiacun, Yanta Road, where there is a Pentax franchise. I heard that it is better. In addition, SEG also has it, but it seems a little expensive, not to mention the one in the mall. Although it must be genuine, the price is a bit harsh. I hope it can really help you.
