What is the reason for the formation of Zheng He worship in Southeast Asia?

In fact, Zheng He was originally a Uighur. His seven voyages to the West did not bring Genghis Khan's war to all places, but the mind and civilization of the Ming Empire at that time. As a supporter behind the long-distance fleet, Judy, the emperor of the Ming Dynasty, did not want to plunder the wealth of other countries by war, but to show the strength and mind of the Ming Empire to the world with the aura of a big country. Therefore, Zheng He, as the leader of his fleet, brought civilization, peace and wealth along the way. Off-topic: The real purpose of Zheng He's seven voyages to the West is said to be that Judy wanted to find his nephew Zhu Yunwen (the son of his eldest brother), because Emperor Wen Jian burned down the Ming Palace, but Judy didn't find his body. There is no clear textual research on the authenticity of this legend, but it is written in modern history.
