Hezuo (Zö) City (Tibetan: གཙོས་གྲོང་ཁྱིར།, ZYPY: Zö Chongkyir; Chinese: 合作市; pinyin: Hézuò Shì) is the administrative seat of the Gannan Tibetan Autonomous Prefecture in southern Gansu province in Western China. It is home to the Gêndên Qöling (Zö Gönba) and its Milaraiba Tower, the Langshangmaio Temple, and a mosque. There is a breed of pig, the Zoi Swine (a.k.a. Silverweed Pig), from here and the whole Gannan TAP also.

The Tibetan name Zö/Hzö གཙོས། is pronounced Dzoi in Standard Tibetan and pronounced Hdzoi/Hdzu in local dialect.
