Why did Chinese officials stop the voyages of Zheng He?

Chinese officials halted the voyages of Zheng He primarily due to a shift in political priorities and the desire to focus on internal stability and agricultural development. After the Yongle Emperor's death, subsequent leaders viewed the expeditions as costly and unnecessary, emphasizing Confucian ideals over maritime exploration. Additionally, the Ming Dynasty faced threats from nomadic tribes and internal strife, leading to a strategic redirection of resources away from overseas ventures.
