Introduction to Stone Drop Rouge: There is a small well next to the Patriarch's seat in the Patriarch's Cave, and the Patriarch drank from the spring water in it. The walls of the well turn bright red due to the spring water, just like rouge seeping out from the cracks in the rocks. They have remained unchanged for thousands of years, which is a great wonder of Miaodao Mountain. Whenever there is a severe drought, farmers from hundreds of miles around come here to collect water and pray for rain.
