Final answer:
Chang Han's ideas influenced the political context for ending Zheng He's voyages by reflecting the Confucian officials' discomfort with foreign influences, leading to China's increased isolationism.
Step-by-step explanation:
The decision to cease Zheng He's voyages can be understood within the political context provided by ideas like those of Chang Han. Chang's opposition to the integration of outsiders into the Chinese noble class parallels the Confucians' discomfort with the disruptive influence of extensive foreign contacts, leading to the closure of China to the outside world. As Confucian court officials determined that Zheng He's voyages were causing too much disruption to the Chinese way of life, this mirrored their broader perspective on maintaining cultural and political integrity by limiting the influence of foreign elements, thus contributing to the political context for the decision to end the expeditions and increasing isolationism that characterized China during this period.
