Dunhuang Museum introduced the development history of Dunhuang through 1 preface hall and 5 exhibition halls from the two Han, Wei, Jin, North and South Dynasties, Sui and Tang Dynasties, Song, Yuan and Ming Dynasties to the Qing Dynasties. If China preserves a civilization that has not been interrupted, and it can continue to integrate places from east to west. Dunhuang should be one of the northwest regions. I want to know more about Dunhuang. Dunhuang Museum is a good choice.
