On the holy mountain of Pilu, there is a cave where the outstanding Tibetan meditation master, literary and translator Piluzhana once practiced here. After going up the mountain, you can see the cave in a faint way, but you don't see the road. After turning a corner, you see a staircase that goes up and down the steep and abnormal stairs. Feifei told us firmly that to enter the cave, you must take this steep staircase. After listening to the legs, you will start to feel soft. The people who practice in the cave are not ordinary people anymore.
