The most famous commodity is Tianlan Tianwei, which is located at Lize Bridge in the West Third Ring Road. I don't know if you want to buy cheaper clothes, because the prices and styles of clothes sold in the tail market and the clothing wholesale market are similar. The biggest and cheapest clothing market in Beijing is the zoo clothing wholesale market. Take the subway to Xizhimen, then take the bus and take one stop. I don't know which district you live in, and there are xiaohongmen wholesale market and Muxiyuan wholesale market, which are also cheaper. At the Muxiyuan Bridge in the South Third Ring Road. See which one is closest to you. Let's go to the zoo if it's cheap anyway.
