Biography
Early Service and the Heroic Boat Rescue
Gu Cheng was renowned for his remarkable stature exceeding eight Chinese feet and martial prowess with sword and bow. During the turbulent close of the Yuan Dynasty, he mobilized a home defense squad before surrendering his force to Zhu Yuanzhang in 1353. Impressed by his integrity and bearing, Zhu Yuanzhang enrolled him in the core bodyguard retinue. During an early amphibious encounter, Zhu Yuanzhang's command boat struck a hidden shoal. Yuan warships closed in rapidly amidst rain of fire arrows. Seeing the mortal peril, Gu Cheng plunged into the mud-choked shallows, braced his back against the hull, and with superhuman physical exertion hoisted and shoved the heavy vessel into deep channel waters. Zhu Yuanzhang marveled at his raw courage, comparing him to the legendary Han hero Fan Kuai. Gu Cheng went on to participate in the reduction of Jiqing, Changzhou, and Ningguo, constantly leading vanguard charges. ### Southwestern Expeditions and Guizhou Governance Following the founding of the Ming Empire, Gu Cheng served under Fu Youde in the southwestern campaigns. In 1381, during the conquest of Yunnan, Gu Cheng led elite reconnaissance columns that bypassed enemy cliff emplacements at Pu'an, delivering a decisive rear assault that dismantled Yuan resistance. Recognizing Guizhou's rugged terrain and volatile ethnic enclaves, the Ming court designated Gu Cheng Assistant Regional Military Commissioner of Guizhou. Gu Cheng governed with strategic restraint, respecting local tribal traditions while establishing garrison colonies (tuntian) to achieve agricultural self-sufficiency. When the Shuixi Miao chieftain A-rong staged an insurrection in 1396, Gu Cheng mobilized eight hundred cavalrymen through an unmapped blizzard route, descending upon the rebel stronghold by rope ladders and capturing A-rong alive. For over twenty years, Gu Cheng commanded such immense local respect that tribal leaders submitted civil disputes to his arbitration rather than resorting to arms. ### The Jingnan Crisis and the Frozen Walls of Beiping Upon the outbreak of the Jingnan civil war in 1399, the Jianwen court dispatched veteran general Geng Bingwen to crush the Yan rebellion. Gu Cheng served as vanguard commander. At the Battle of Hutuo River, Ming imperial lines collapsed under Zhu Di's coordinated night assault, and Gu Cheng was taken prisoner. Recognizing Gu Cheng's unimpeachable stature among Ming veterans, Zhu Di personally cut his bonds, draped him in an imperial silk robe, and declared that heaven had bestowed a wise mentor upon him. Entrusted with preserving Beiping alongside heir-apparent Zhu Gaochi, Gu Cheng formulated the siege tactics against Li Jinglong's 500,000-man grand army. Observing freezing winter gales, Gu Cheng instructed the defenders to continuously pour well water over the masonry battlements. The ramparts transformed into sheets of frictionless ice, rendering imperial siege ladders and scaling hooks useless. Simultaneously, coordinated sorties ignited enemy supply depots, causing Li Jinglong's forces to abandon their siege in utter disarray. ### Later Honors and Eternal Memorial in the Southwest Following Zhu Di's ascension as the Yongle Emperor, Gu Cheng was enfeoffed as Marquis of Zhenyuan with an annual stipend of 1,500 shi of grain. Entrusted once again with the military governance of Guizhou, Gu Cheng spent his remaining years expanding courier roads, constructing schools for chieftain families, and laying the infrastructural foundation for the formal establishment of Guizhou Province in 1413. He passed away peacefully in 1414 at the age of eighty-five.
