Who made the rules in The Journey to the West and how did he manage them?

In Journey to the West, the Tathagata Buddha is the rulemaker.

There are three major forces in Journey to the West: Buddhism, Heaven and Monsters.

I compare them with the company, for example, Buddha is the boss of the company, Guanyin Bodhisattva is the CEO, other Buddhas and Bodhisattvas are the managers or directors of the company, and the following Lohan and Misha are ordinary employees of the company.

Paradise is another company that has close business relationship with Buddhism. Those monsters are scattered small companies.

The process of learning from the West is a large-scale recruitment process. At the order of Tathagata's boss, the CEO of Guanyin Bodhisattva implemented it, and other departments were responsible for assisting, and Tiandao Company was invited to assist in inspecting five Tang Taoists to determine their positions. The process of learning from the experience of the five Tang Priests is the content of the investigation, which is equivalent to the merger and acquisition of small companies.
