The Yongle Emperor instituted a Ming governor on Luzon during Zheng He's voyages and appointed Ko-ch'a-lao (許柴佬; Xu Chailao) to that position in 1405. China also had vassals among the leaders in the archipelago. China attained ascendancy in trade with the area in the Yongle Emperor's reign. The local rulers on Luzon were "confirmed" by the governor or "high officer" appointed by the Yongle Emperor.
