There was Yu Lao in the world, who traveled to hundreds of rivers, was proficient in Confucianism and Taoism, had the talents of Qilin, and the talents of Wolong. It is said from generation to generation that "the world is in chaos, but Yu Lao is at peace". However, it is hidden in Zhang'e Mountain, with half an acre of black bamboo and three thatched huts, where it is accompanied by fish and birds all day long. Outside the house, thousands of people prayed. However, there are no scales on the dragon's tail. Therefore, the virtuous kings and hegemons of various countries find another way.
Mr. Yu has three disciples. They are gifted and intelligent. They inherit Mr. Yu's talent and inherit the legacy of a good teacher. They have the potential to surpass others. It is rare to find them but they can be found. Let me ask why these three people are: Mu Yu, the son of Yue Xiangguo, Qian Feiyu, the son of Lang Fujia, and another person named Yu Ling, who is the surname of his master, but his nationality is unknown. But look at how these three people can turn the tide and guide the country.
