Some Tianjin locals consider it to be Tier 1 . I think most of us just say ok, SH BJ GZ SZ tier 1. Then Chengdu, Nanjing, maybe Tianjin and Chongqing and Wuhan, and the rest 3 or below. TJ ren are all too rich for their own good, but the development of the city is not on par with any of the others IMO.
