What religion did Zheng He believe in?

Regarding Zheng He's main religious beliefs, there are Islam, Buddhism (Tibetan Buddhism), Taoism and other views, and the academic community has not yet reached a conclusion. Islam calls it "the epitaph of the late Ma Gong". "Xiangbei in the Tomb of Muslim Sages in Lingshan, Quanzhou" and other basic materials, combined with the textual research and interpretation of "Three Guarantees" and the investigation of Zheng He's related activities (spreading Islam, returning to China, requesting the restoration of Jingjue Temple, and asking his son Sun Shishou to keep it, etc.).

According to Buddhist records, in the first year of Yongle (1403), Zheng He was accepted as a disciple of Bodhisattva by Yao Daoyan and monks, and his dharma name was Fu Jixiang. Zheng He also printed the Tripitaka Sutra and left an inscription before his death. He once asked Yuan Yun, a famous monk, to copy the Wonderful Dharma Sutra with gold powder. Postmortem cremation is also considered as an example of Buddhist belief.

Taoism emphasizes the connection between Zheng He's voyages to the West and Tian Fei's beliefs, and some scholars start with Zheng He Tower (Hongjue Temple Tower) to analyze it.

When Zheng He was young, he served Prince Judy. He is smart and resourceful, knowing the soldiers and learning to fight. Later, he made meritorious service in the battle of Jingnan and was promoted to be the eunuch in charge of the internal officer. From 1405 (the third year of Yongle) to 1424 (the twenty-second year of Yongle), Zheng He made six expeditions to the Western Ocean as a eunuch, and later served as a eunuch stationed in Nanjing on 1425 (the first year of Hongxi), and 1430 (the fifth year of Xuande) was ordered to disembark for the seventh time.

Zheng He's voyage to the West was an unprecedented feat in the history of world navigation at the beginning of the15th century, which played a positive role in economic and cultural exchanges between China and foreign countries. Zheng He himself showed his diplomatic ability, military strategy and spiritual quality in this historical event, and won the respect and commemoration of the world. Since the late Qing Dynasty, Zheng He's research has developed rapidly, but many important topics are still inconclusive.
