What is the origin of the old monkey who showed the Monkey King the golden hoop and worshipped Bodhi as his teacher?

The old monkey who instructed the Monkey King to get the golden hoop and the Monkey King to learn Bodhi was actually a Tongbei ape. This old monkey is actually one of the four bastards mentioned by the Tathagata Buddha. These four monkeys are Ling Ming boulder, Akasaka, Bronze Ape and Liu Er Macaque. Of course, the Monkey King, which we are familiar with, actually belongs to the first kind of Ling Ming boulder. We can see that this once-back ape is actually on an equal footing with the Monkey King.

Then someone may ask, since the Monkey King is on a par with him, and his technology is very high, why not unify the whole Guo Huashan, but help the Monkey King? In fact, this old monkey is the former monkey king of Huaguoshan. Now Tongbei ape is very old and has no energy to manage the whole Huaguo Mountain. For Tongbei ape, there are more important things waiting for him to do now, so he must cultivate a new the Monkey King to manage the whole Huaguo Mountain at this time, and the Monkey King, the stone monkey, is undoubtedly the best choice.

It can also be seen from this point that the old monkey king Tongbei ape is actually a very responsible monkey, who has been thinking about the future of Huaguoshan. With the help of Tongbei Ape, the Monkey King came to Bodhi's ancestor for the first time and learned a lot of skills. After returning to Huaguo Mountain, with the help of Tongbei Ape, I came to the Dragon Palace in the East China Sea and got my best weapon, Ruyi Golden Hoop.

After getting the golden hoop, the Monkey King can be said to be like a duck to water. At that time, the Monkey King claimed to be the Great Sage of Qi Tian, and then there was chaos in the Heavenly Palace. Of course, all this is actually just a plan of the Buddhist community, mainly to let the Monkey King accompany Tang Sanzang to learn from the scriptures. Later, the Monkey King achieved great success and became one of the 35 Buddhas in Lingshan. It can be said that the Monkey King's high achievement must have benefited from the help of the post-ape.
