Does anyone know where there is a 1080P projector in Guiyang that costs about 10,000 yuan?

There must be. There are several large digital shopping malls in Guiyang, near the Great Cross Bridge and next to KFC. You can go to Grand Cross Station or Hundred Flowers Theatre by bus.

There is also Brain Baixin Computer City, which is very close to the new world and next to Metropolitan Road (Zhongtian Business Building).

Others are Guizhou Computer City at the intersection of Shenqi Road and Guanxing Road. Yixin Cyberport, next to Daximen, next to Guiyang No.8 Middle School.

I suggest going to the first two. I hope you can buy it.
