We traveled by ourselves, arrived at the ground, collected tickets through the Internet window, and walked for 20 minutes to the entrance of the Rift Valley. It was very beautiful. There were underground Dragon Palace, Donghai Dragon Palace, sightseeing platform and waterfall. They were beautiful and magnificent. We bought drifting tickets and raincoats. The drifting of the Taian Rift Valley Cave was very slow at first, the slow water flow was very fast, the feeling of sitting on a bridge was fun and exciting, and there were vendors. West is as good as walking a maze. Out of the rift, we go to see fish in the year of lotus. We feed fish, there are many fish, there are red goldfish, goldfish and black fish. We are as close as we can get. I went to the migratory birds to fly, and saw the big white geese. It's a good trip, but it's a pity that I didn't go to the playground. Next time I go.
