You can only buy Xinyang Maojian tea. You can go to the tea market on Hanghai Road or Guoxiang Tea City, which is cheaper. The famous Xinyang Wenxin Teahouse is good (there is a big one at the intersection of Jinshui Road and Jingsi Road).
Nanyang Valley wants to buy Weft 3 Road. Near Weisan Road, Zhengqi Street, is an old street selling jade articles. If you want a brand, it is a jewelry store, something that really understands Baoyu.
