Ранняя Лян
Zhang Mao (; 277–324), courtesy name Chengxun (成遜), formally Prince Chenglie of (Former) Liang ((前)涼成烈王) (posthumous name given by Han Zhao) or Duke Cheng of Xiping (西平成公) (posthumous name used internally in Former Liang) was a ruler and the commonly accepted first ruler of the Chinese state Former Liang. (Former Liang being a state that transitioned from a Jin Dynasty governorship to an independent or semi-independent state that vacillated between being a Jin vassal and being a vassal of the stronger state controlling the Shaanxi region – Han Zhao, in Zhang Mao's case – it is difficult to define a single founding date or founder for Former Liang; but Zhang's general pardon of the people in his domain when he became ruler was considered by many historians as the sign of effective independence from Jin.) During the brief reign of his grandnephew Zhang Zuo, he was honored as Prince Cheng of Liang (涼成王).
