Many people think that heaven is incompetent, and all the gods in the sky are no match for a monkey. Only by inviting the Tathagata to the Western Heaven Lingshan can the Monkey King be subdued. In fact, these are all illusions. The Monkey King has played all kinds of civilian immortals, and some roles with low mana. Those powerful masters in the sky didn't really do anything. They either watch and stand by, or put water on them and pretend to be defeated.
For example, the two great gods, Tai Shang Lao Jun and Nezha, are both above the Monkey King, but they all pretend to be defeated by water, and then let the Monkey King play tricks. But they also know that the Monkey King can't afford to lift any big storms at all, depending on how the Jade Emperor responds.
The Jade Emperor, as the Lord of the Three Realms, governs all the forces under his command, and most of these forces are orthodox immortals. But in the face of the monkey's nonsense, they all work hard, even pretend not to know, and there is slack, which is definitely a big problem.
So when the Monkey King hit the door of Lingxiao Hall and Wang Lingguan stopped him, he decided to try forces other than immortals, and sent someone to the distant Buddhist paradise to order the Buddha to deal with the Monkey King. After the Buddha appeared, he easily subdued the Monkey King and showed his loyalty to the Jade Emperor.
The Jade Emperor was very satisfied with the performance of the Tathagata Buddha, so he held a banquet to celebrate his success. The Tathagata Buddha also understood the meaning of the Jade Emperor and named the banquet as a guest of honor. An Tian convention? This is my contribution to Lingshan Buddhism. Since the Taoist immortals of the old school don't really want to work for the Jade Emperor, fill their seats and let Buddhism help you decide the sky.
In fact, the Monkey King's disturbance in Heaven is an introduction. His spoiler reshuffled the forces of heaven, and Buddhism began to rise and gradually competed with Taoism. At the same time, it also implies the evolution of the competitive power of Buddhism and Taoism in the world.
