There are thousands of mountains in Yunnan and Guizhou, and there are many dangerous passes. The refugees who flee into the mountains are often very rare. Some people just disappeared in the endless mountains and forests, some lost their lives to the claws of wild beasts, and some fell into prey of evil spirits in the mountains. A group of people like this were wandering among these dangerous mountains. They do not enter Taoism, do not practice magic, do not help poor sentient beings, and do not intervene in worldly causes and effects. They only take coarse grains and clean water as reward. He does not go into the mountains during the day and does not enter the village at night. He does not tell the news of the living, but only reports the news of the dead.
The mountain people in the mountains are awe-inspiring and unfamiliar, and have been called mountain passers for generations.
