Journey to the West, why did the Monkey King never hurt Nezha?

Because the Monkey King and Nezha have a good relationship.

Nezha was originally the stone essence used by Nu Wa Empress to fill the fairy stone, but it was used to fill the fairy stone itself. Shi Ling was reincarnated as Nezha, the third prince of Li Tianwang's family. The Monkey King itself is a colorful stone left by Nu Wa Empress when she mended the sky. It is Taoism that carefully cultivates in Huaguo Mountain, absorbs the essence of heaven, earth, sun and moon, produces spiritual wisdom and becomes a stone monkey.

The Jade Emperor knew the Monkey King's background and learned from him, so he was patient everywhere and didn't dare to lay hands on the Monkey King. As the etiquette around the Jade Emperor, Nezha must also know the identity of the Monkey King. In particular, the Monkey King's various martial arts magical powers show the shadow of Bodhi's founder everywhere. As a Taoist priest, Nezha must be very familiar with Bodhi. He saw the Monkey King's apprentice, so he can't be serious.

Both of them have a skill, and both are young people. With the Monkey King's lively and active personality, they certainly have a lot to do with Nezha in the sky. You know, the Monkey King loves to make friends and has a good relationship with many immortals in the sky. Especially during the Monkey King's management of Flat Peach Garden, it is estimated that Nezha didn't go less. After all, he is a child, and it is reasonable to love fresh peaches.

The Monkey King vs Nezha:

Wukong said, "I just stand still and let you cut some swords." Nezha was furious and shouted, "Change!" That is, he became a three-headed and six-armed hero, holding six kinds of weapons, namely, demon sword, demon knife, demon rope, demon pestle, hydrangea, fireball, ya ya fork and face beating.
