During the Ming Dynasty (13681644), a Ming emperor conferred seven surnames upon the Jews, by which they are identifiable today: Ai (艾), Shi (石), Gao (高), Jin (金), Li (李), Zhang (張), and Zhao (趙); sinofications of the original seven Jewish clans family names: Ezra, Shimon, Cohen, Gilbert, Levy, Joshua, and Jonathan, respectively. Interestingly, two of these, Jin and Shi, are the equivalent of common Jewish names in the west: Gold and Stone. (See here)
