What is the general price for taking a photo in Nanjing?

There are many places to take pictures underground in Laidi, Xinjiekou. Students have all taken photos, and there are more than 300 ~ it seems that there are 1 and 2 sets of clothes, more than 500 are three sets of clothes, and more than 700 have six sets of clothes and six styles. You must make a counter-offer when you go there. You can get a lot of discounts. My classmates took photos in Yishan. Not bad, but it's a bit slow to make an appointment in advance ~
