from where I can purchase ladies sweaters and coats and cosmetics and good quality Jewllery in guangzhou?

For clothes of god quality and reasonable price, I suggest you go to the clothing markets near GZ Railway Station, where you will have more choices and sometimes bargaining is ok! For cosmetics, Beauty Exchange Center (Meibo Cheng Cosmetics Wholesale Market) is recommended. For jewllery, you are advised to find at local Liwan Plaza near Xiajiu Lu.
