A thousand miles away, just to arrive at this moment, standing at the top of the mountain at 4090M above sea level, thousands of reddish huts overlap, surrounded by several magnificent halls like the arched moons of stars - it is the Saidafo College hidden in the deep mountains, the largest Tibetan Buddhist College in the world. It is the red house that I often miss in my heart. Originally, it is just like this in front of me. Sedavo College belongs to Ningma School. It was founded in 1980 by King Pengtuofa of Jinmei. In a few years, Sedavo College rose rapidly from the depths of the valley and became the largest Tibetan Buddhist College in the world. The wooden houses in the mountains may be a good visual enjoyment for the tourists, but there are hidden dangers for the monks who live in them. In order to improve the facilities and poor life of teachers and students in Colleges and universities, it is quite necessary for monks to practice more comfortably, demolish some wooden houses and turn them into small buildings with fire-fighting passages, bathrooms and so on. . On the one hand, there are hidden dangerous red-building wooden houses, on the other hand, there are public houses and monasteries to be built.
