Tell you the general consumer price
If you are in Kaili, eating authentic, one person twenty or so dollars or so. In Guiyang I eat more often times is the restaurant behind the environmental protection guest house, fish by the pound, thirty or so yuan a catty, the rest free. I should say that in Guizhou province is mostly this price.
In other cities it will be relatively expensive. For example, Nanchang, we ordered two and a half pounds of fish, check out 120 yuan (plus a bottle of drink)
In Guangzhou tried a house called Huangguoshu, the consumption of two people is more than a hundred points or so. The fish is so small, maybe just a little more than a pound.
