Today, I went to No. 34, which is very convenient. It was only an hour before I sent it out. When I came back, I heard that the annual ticket for Beijing Scenic Scenic Area, which I bought, was worth a hundred yuan and forty-two scenic spots. The cave was beautiful and a little damp and cold, but I walked all the time without feeling cold. Sometimes I heard the rumbling voice, a little scared. I walked for about two hours, and arrived at the second floor in about one hour. You can continue to walk on the third floor and the fourth floor, but you can go straight up and out of the hole if you are tired. There's a place for free photography. When you go out of the hole, you get a two-inch-sized one. You can't see it clearly. If you want a big one, you can buy one for fifteen yuan.
