Among the rebel leaders who appeared in the Huai area after the 1351 floods was a more ambitious man than Fang Kuo-chen, named Chang Shih-ch'eng 張士誠 (1321-1367).

Native to the Kao-yu region of modern Kiangsu province, north of the Yangtze, Chang and his brothers grew up as canal boatmen employed by the state salt monopoly.]
