Tianshan is a giant multi-level complex devoted to tea. The market hosts around 150 stalls selling thousands of varieties of leaves. Walk into almost any of these shops and soon enough you'll be sitting with a small cup, infusion after infusion being poured out for you to try. It's a 20 rmb taxi ride from People's Square or a solid 10 min walk from Line 3, the mall looks something like a temple from the outside.
