Why is Dapeng goldfinch the Tathagata's uncle?

It is said that Feng gave birth to two sons, a peacock and a Dapeng, which harmed the world. Peacock swallowed Sakyamuni Buddha who was practicing under the bodhi tree one day. When Sakyamuni just realized the positive result, he broke out from the peacock's back, surrendered the peacock, regarded it as the Buddha's mother, and later persuaded Dapeng, so from this perspective, Dapeng is also the Tathagata's uncle.

In the journey to the west, the lion camel bell, the golden wing Dapeng carving is really powerful, and he is threatened to be the Buddha's uncle. The Monkey King directly found the Tathagata. The Tathagata said, "From then on, people were born in children, the earth was born in ugliness, and life was born in yin. When heaven and earth met again, everything was born. Everything has birds and beasts, animals are as long as Kirin, and birds are as long as phoenix. The phoenix has the spirit of intercourse again, giving birth to peacocks and Dapeng. Peacocks are the worst when they are born. They can eat people and suck people for 45 miles.

I was at the top of the snowy mountain, refined into a golden body, and he has sucked me down. I want to get out of his private door for fear of polluting my body; I cut open his back and climbed up Lingshan. If you want to hurt his life, you must be persuaded by the Buddhas to hurt the peacock like you hurt my mother, so you left him at the Lingshan meeting and made him a Buddha mother, peacock, king Daming and bodhisattva. Dapeng and he were born of the same mother, so they are related. "

In the The Journey to the West, Dapeng Bird appeared as the Big Devil, the three big days in the Lion Camel Cave, the Wang Peng Devil, nicknamed Yunpeng. The description of the shape is a mixture of Indian mythology and China and Zhuangzi's article: "Golden-winged Kun has a head and a leopard eye with a star eye. Zhenbei Tunan is strong and brave. Feitian, XiaoLon is miserable. A hundred birds hide their heads when the wind blows, and when they lose their hearts, they loosen their claws. This is Dapeng sculpture, with a cloud tour of 90,000. "

What he did was, first, he ate up all the people in the lion camel country and a city 500 years ago, seized the country, and became king himself. I heard that the Tang Priest wanted to eat Tang Priest's meat, but I was afraid that Monkey would be too powerful to do it alone. So, I went to the lion camel cave and became brothers with the lion elephant, forming an alliance to capture the Tang Priest. One country and one hole form a corner with each other, and the geographical position is favorable, so that the monkey is caught by mistake.

The Monkey King has the means to subdue lions and elephants, but he can't do anything about the Dapeng bird that can't escape. Dapeng bird flies faster than the Monkey King's somersault cloud, with nine Wan Li wings, and catches up with the Monkey King with its wings. Finally, please ask Tathagata to shoot down the Dapeng bird.
