In which direction is Yue Lao?

Yue Lao is in the southwest. At the beginning of the Southern Song Dynasty, there was a scholar named Gan, who was in his twenties and had not mentioned his relatives. Once his friend asked him to beg a crazy monk who lived in the street. The dry scholar found the crazy monk, and the crazy monk said that Yue Lao didn't tie a red rope for you. It's none of my business. Ask Yue Lao. The dry scholar said with a bitter face that the big monk said it was a joke. I am a mortal. Please tell the monk clearly how to meet Lao Yue. The mad monk motioned for him to put his ear in and whispered that it was easy to see him. On the full moon night in November this month, you went to a mountain in the southwest outside Beijing and saw a drunken old man lying on a boulder at the top of the mountain, that is, Yue Lao.
