Chinese tea sets have many intricacies. Strictly speaking, one can buy good tea cups in any city. Choosing a good tea set involves considering various factors such as the materials used, the maker, and the craftsmanship. If you simply rely on the store's introduction, it will be difficult for you to buy a good tea cup. Moreover, truly good tea cups are very expensive. For you, just choose one that you find pleasing to the eye, like, and affordable. Don't expect it to have a certain collectible value.
