The afternoon of Aug 19th, General Secretary Xi Jinping, who was inspecting in Gansu, came to the National Key Cultural Relics Protection Unit and the World Cultural Heritage Dunhuang Mogao Grottoes to learn about the protection and research of the Mogao Grottoes, and went into the caves to observe the long-established colorful sculptures and murals. The masses who were visiting the tour saw the general secretary come, cheered excitedly, and greeted the general secretary. Xi Jinping took the initiative to go forward, warmly shook hands with everyone, and asked them where they came from? If the road is far away and the cost is high? and said I wish you all a pleasant trip. A visitor told the general secretary that they took a special trip to see Mogao Grottoes from Jiangsu. The general secretary said to him with a smile: "Very good, you can see a lot along the way, the children can enrich their knowledge."
