Xie Tiandi, a hermit of Wudang in the Song Dynasty. I don't know its name. According to the "Great Mountain Taihe Mountain Annals" and the "Junzhou Annals", citing the "Wudang Biography", this person lived in seclusion in a stone cave on the sheer cliff at the foot of the South Rock Dressing Platform (also known as the Dressing Platform) to practice fasting and cultivation. The cave where it is located is inaccessible to people, not even 麞 elk can climb. But he flew with ease, as if walking on flat ground. Although this stone is extremely dangerous, it is easily visible to pilgrims and tourists. Every time someone was seen in the cave, someone would call out from afar. When asked briefly, they remain silent; when asked frequently, they merely say, "Thank goodness!" Over time, people began to call it "Xie Tian Di". The cave where he lived was called Xie Tiandi Rock. This acupoint still exists at the foot of the changing platform on the South Rock. Later, Xie Tiandi achieved immortality and passed away, with no one knowing where he went.
