Dunhuang history and the mystery of historical figures becoming Buddha

Dunhuang was famous only because it was close to Yumen Pass, because its geographical position was important (Zhang Qian passed by here when he was on a mission to the Western Regions in the Han Dynasty, and the exhibition began only after a large number of immigrants poured in at the end of the Han Dynasty. Dunhuang was the capital of the western regions in the Eastern Han Dynasty. There is a Mingsha Mountain 25 kilometers away from Dunhuang (wind and terrain make sounds, and ancient times thought there were immortals on the mountain). Later, a very prestigious monk came and saw the Buddha's light (sunset) on the hill. By the Northern Wei Dynasty, it had become a military center, and the court sent several officials to manage it. These officials respected Buddhism, not only promoted Buddhism, but also invested in opening caves to build Buddha statues, and began to form the embryonic form of Buddhist culture in Mogao Grottoes! In the Sui and Tang Dynasties, exchanges with the western regions became more frequent, and it became an important transportation hub, with diversified development of culture and economy and extensive contact with Buddhist personnel! The Mogao Grottoes reached its peak, and later Tubo took advantage of the An Shi Rebellion to occupy this place. In order to appease the people and promote Buddhism, we know that there is a monk official system in Tubo, and monks as managers enrich the Buddhist culture here! As for the Cheng Foer you asked, I have never heard of it. Later, I checked, this figure is fictional, just to use this person to describe the character modeling of Dunhuang murals! This man is a maiko of Datang!
