Introduction to Tianqiao Cave: Legend has it that it was the place where Li Daxian with long eyebrows practiced practicing while facing the wall. To enter this cave, you must cross a mountain stream. The stream is a hundred feet wide, and its cliffs are like chisels, blocking the way like a natural chasm. There is an iron plate that spans the stream, but it is only wide enough. Tourists are intimidated and many dare not step into it.
