Now we are going to walk through the rainbow bridge with a span of more than 50 meters. It is a pure rock structure. It is said that the great emperor Zhenwu was about to succeed in the cultivation. On the 9th day of the ninth month of the Chinese lunar calendar, in the early morning, the prince was still sitting cross legged for cultivation. However, he felt that his heart was very clear. His chest was like crystal, and his body was like a cloud, which could fly at any time. He was in a trance to know that this was his way, which was about to take off. At this time, the prince stood up and stretched his body. Suddenly a beautiful woman came to him. The beauty was thin as a cicada's wings in her dress and carried a cup of fragrant tea in her hand. The beauty asked the prince to use tea. She said that the prince meditated all day long, his clothes were worn out, and there were grass branches with birds in their hair. She said that she wanted to dress the prince. The prince stopped her and asked her to do what she wanted, not to be frivolous. As soon as the beauty heard this, she became angry and pointed to the prince and said, "you are so cruel. You treat my kindness like a donkey's liver and lung! I don't want to live.". Say, run to a big stone on the edge of cliff, want to jump down. As soon as the prince saw it, he ran to her and stopped her. He said, "the life of people is great in the world. Even if there is evil thoughts, it will not be too much. Just change it.". Who knows, that beauty does not listen, or jumped off the cliff. The prince was shocked. He thought that after forty-two years of cultivation, the road would be completed. If he jumped down to save people, he would inevitably be crushed to pieces. But if he didn't go to save people, he would become immortal. What's the use of that? He thought that the prince would also jump off the cliff to save people. Who knows at this time, there is a cloud in the deep valley. Five dragons in the cloud hold the prince and fly up to the sky. It turns out that on the day the prince ascended to heaven, the beautiful woman was dressed up by ziyuanjun, the goddess of heaven. She wanted to try out whether the prince eradicated all hearts. It's said that the prince jumped down here to become an immortal, and a rainbow appeared here, which lasted for a long time. This bridge was built to promote the true God of Taoism, Zhenwu emperor.
