Introduction to Sanfeng Cave: Bayue Mountain is a place of Taoism. It is said that the founder of Taoism, Zhang Sanfeng, lived here to practice martial arts. According to legend, Zhang Sanfeng took a fancy to Bayue Mountain while traveling in all directions, so he dug a hole in the cliff halfway up the mountain to practice for a period of time. As soon as he came, the mountain people were no longer as afraid of jackals, tigers and leopards as before, and they came to the mountain to collect firewood. Zhang Sanfeng unexpectedly found that many children came to collect firewood every day. He thought: Why not go to school and learn to read? After understanding it, I learned that it was caused by being too poor. For this reason, he asked the children to come to his cave to study without taking any money. Perhaps because of the fairy spirit, children coming to the cliff to study are like walking on flat ground. The Sanfeng Cave, which is about five square meters in size, actually accommodates hundreds of children. Therefore, folk songs such as "Zhang Sanfeng performed extraordinary feats and taught children in Sanfeng Cave" are widely circulated.
