Yang Guijingshan, a young official of Guanglu Temple, was an official of Kangxi Dynasty. He used to be the magistrate of Gu 'an and participated in the regulation of Yongding River. According to the usual practice, as soon as the autumn flood season is over, construction will begin. At that time, the river in Yongding was Huangmou, because the tribute money was uneven and it was dragged on until winter. (Yang Gou sees migrant workers) My legs shook when I waded in the water this morning. Yang Jingshan sympathized with them and allowed them to work after sunrise. Later, Huang visited the construction site and thought that migrant workers would be whipped if they were late. Yang Gong argued, but failed to stop him. He went directly to lead his horse and took it to a cold place and said, "Where you can go, migrant workers can also go. Now that the sun has risen so high, you are still shivering in a thick fur robe, but do you want to punish these barefoot people who come to work in Dai Yue? " Huang was furious and wanted to impeach Yang Lou. As it happens, the Governor Li Wenzhen passed by Liu's door and asked about it. Summoned him (Yang Lou) and said, "You can do this at a young age, just like Ren Yan in ancient times." (Later) set up a banquet to entertain him, then take off his fur coat and put it on him, and things will be solved. (Later, Yang Lou will be transferred to Wanping. When Saint Zu visited the southern part of Beijing's jurisdiction, Gu 'an villagers scrambled to beg Saint Zu to let Yang Lou stay in Gu 'an. The holy father asked, "What about another good official in Gu 'an?" A woman replied, "Why don't you give Wan Ping the good officer you mentioned? The wise man smiled and thought she was honest. Just let (Yang Lou) enjoy the salary of the well-known level, and let Yang Lou be the magistrate of Gu 'an County.
