Why can't the Monkey King beat Hong Haier?

Many people ask this question and have different opinions.

1, the Monkey King saw that this was the child of his sworn brother Niu, so he didn't work hard. According to China's traditional culture, it is difficult to do it because of his feelings.

2. the Monkey King entered the kitchen of Taishang Laojun in his early years and was born afraid of fire (especially eyes).

3. One of the most interesting sayings now is that the Monkey King can become a fighter to defeat the Buddha just like the employees in the probation period now, and Hong Haier, as the child of an acquaintance, wants to help the Monkey King, so he can ask Guanyin to accept it and let Hong Haier become a full member like himself. ...

As a child, Hong Haier can't take things lightly. If he loses face, he will probably kill the Tang Priest first and eat the meat instead of staying. The Monkey King wants to play tricks, but he is too clever to hold Hong Haier.

But personally, I prefer the last statement:

After the Buddha turned to Wuzhishan to suppress the Monkey King, letting the Tang Priest accept him did not make him fully recover. No matter how powerful a person is, he has been fighting for 500 years without eating or drinking less (eating copper pills and drinking iron juice), and his physical strength is definitely insufficient.

On the other hand, it is also crucial that the golden hoop on the head affects the exertion of the Monkey King's strength. After wearing the golden hoop, the Monkey King didn't get worse, and many means were never used when the heaven made trouble.

That hitting Honghaier only shows that this imprisonment is a bit too strong.
