To be honest, selling clothes in Zhongshan is not a very good idea. You can think of something else, because Zhongshan is originally a clothing production base, clothing factory and water washing factory. It is convenient to purchase goods, but others know the price. There are too many clothing wholesale markets in Zhongshan. I have been to Shaxi and the clothing wholesale market in the city. They are also sold at retail price, which is very cheap.
There are also many booths. Bought 15 pairs of jeans.
Suggest selling something else. It's rare there I don't think the clothes are very good anyway. There are too many clothing stores in Zhongshan.
You can learn to make syrup and snail powder there. I'm in Suzhou. We don't have these here.
