How did the Monkey King know Niu Wangmo?

In the novel, it is the third time that all the oceans and Qian Shan are arched, and nine secluded places and ten categories are deleted from the list:

When the Monkey King was king in Huaguoshan, he took a golden hoop from the Dragon Palace and worshipped Niu Wangmo. The original text reads: "Travel around the world every day and enjoy the money mountain. Shi Wuyi, visiting heroes all over the world; Miraculous, make friends. At this time, there will be seven other brothers, namely Niu, Jiao Lich King, Peng Lich King, Lion Camel King, the Monkey King, Wang, and even his own seven the Monkey King. Talking about literary criticism and martial arts day by day, walking and preaching, singing and dancing, going back and forth, all of them are unhappy. The distance from Wan Li is only the road to the palace. The so-called nodding way is more than 3,000 miles and twisting the waist is more than 800 miles. "

Later, on the fourth visit, the official's name was Bi. He changed his name for himself and put up a famous signboard:

But he said to his six brothers, "Since my brother is called Monkey King, you can also call him Monkey King." Inside, Niu Wangmo suddenly shouted, "My good brother is right, so I will call him Dasheng." Jiao Mo said, "I am the Great Sage of Fuhai." . Peng Gong said, "I call it the Great Sage." The lion said to him, "I am the Great Sage who moved mountains." The Monkey King: "I call it the ventilation sage." King Yu Zhou said, "I call it an exorcist." At this time, the Seven Saints went their own way, claiming to be their own names. After playing for a day, they ended up separately. "
