Why didn't the Ming naval expeditions continue?

The Ming naval expeditions, led by Admiral Zheng He in the early 15th century, did not continue primarily due to a shift in political priorities and resource allocation. After the death of the Yongle Emperor, subsequent rulers focused on consolidating power and addressing internal issues rather than pursuing maritime exploration. Additionally, Confucian scholars promoted agricultural stability over trade and military expansion, leading to the dismantling of the naval fleet and a decline in maritime activities. This change in focus marked a significant shift away from the expansive maritime policies of the earlier Ming period.
