During the Spring Festival, when I used to play, I took a taxi to the place where I took the cable car. Then I went up. I felt that I had been walking for a long time and I was really tired. In fact, the car could still drive up. It was drizzling and somewhat cold, but the air in the mountains was quite fresh. Several venues, entered and saw some astronomical equipment, as well as star paintings, just met the private guide invited by others in the explanation, followed by a while, or quite interesting, they do not understand what.
