The most interesting thing in "Journey to the West" is the Niu Devil King's family, the Niu Devil King, the Iron Fan Princess, and the Red Child's family live in different places, the Bull Devil King lives in Jilei Mountain, the Iron Fan Princess lives in the Basho Cave of Cuiyun Mountain, and the Red Child lives in the Huoyun Cave of the Dead Pine Stream of the Horn Mountain, and the family of three has its own mansion, which shows that it is not an ordinary mortal monster.
The bull devil king family of three, the most interesting should be regarded as the cow devil king, the bull devil king is Sun Wukong's brother, Sun Wukong did not help Sun Wukong when he made a big fuss in the Heavenly Palace, Sun Wukong was pressed under the Five Elements Mountain, he did not come to see Sun Wukong, when Sun Wukong's master and apprentice arrived at the Flame Mountain, the Bull Devil King immediately turned his face, completely disregarding the brotherhood of the year, it can be seen that the Bull Devil King is a person who sees profit and forgets righteousness.

And the Bull Devil King himself is very interesting, there are also many questions, the Bull Devil King likes the Iron Fan Princess in the end, if he likes, why will he live in the Jade Face Fox's Jilei Mountain, if you don't like it, when the Iron Fan Princess is in danger, he gave up the Jade Face Fox and ran back to Cuiyun Mountain, and fought against Sun Wukong and his party with the Iron Fan Princess, and finally failed to be taken away by the Buddha of Rulai.
First of all, let's analyze why the Bull Demon King lived in Jilei Mountain. When the Bull Demon King and the Iron Fan Princess were together, the original did not mention, but the high probability should be after Sun Wukong made a big fuss in the Heavenly Palace, the Bull Devil King should also be terrified when he saw the end of Sun Wukong, so he no longer called himself the Great Sage of Pingtian, and by chance, he met the Iron Fan Princess, and lived in Cuiyun Mountain, and later there was a red child, who should have been a happy family, but why did he go to the Jade Faced Fox? Is it just that the jade-faced fox looks good?
The land gave the answer: "Hercules is the husband of the lady of the Rocha." He had skimmed the Luosha and now the Moyun Cave of The Thunder Mountain. There was a viva fox king, and the fox king died, leaving behind a daughter named Princess Jade Face. The princess had millions of furniture, no one in charge, two years ago, with the Bull Demon King's miraculous powers, he was willing to accompany the furniture and recruit a husband. The bull king abandoned the Rakshasa and did not look back for a long time. It can be seen that the Bull Devil King may not only be because of the beauty of the Jade Faced Fox, after all, the goblin will not grow old, but looks at the millions of furniture of the Jade Face Fox, and this once again proves that the Bull Devil King Bull Devil King is a profit and forgetful of righteousness, with the Million Furniture of the Jade Face Fox, he abandoned the original Iron Fan Princess and lived in the Thunder Mountain.
Princess Tiefan did not come to invite the Bull Demon King, why did the Bull Demon King return to Cuiyun Mountain? It turned out that Sun Wukong stole the Cow Devil King's water-sheltering golden eye beast, turned into the appearance of the Bull Devil King, and went to the Iron Fan Princess to cheat the Banana Fan, and the Bull Devil King saw that his mount was stolen, so he guessed that Sun Wukong had deceived the Basho Fan, and with the character of the Bull Devil King, he certainly could not suffer losses, so he immediately returned to the Basho Cave, saw the Iron Fan Princess, and asked Sun Wukong to settle the account after asking the original commission.
Later, the Bull Devil King, Sun Wukong for the banana fan fight you and me, the Bull Devil King also lost the Jade Face Fox this place, the Jade Face Fox was also killed by the Eight Precepts of the Pig, and the Bull Devil King continued to fight with Sun Wukong, what he did not expect was that the Buddha also sent people to deal with the Bull Devil King, and finally was subdued by Nezha, and the Bull Devil King submitted to the Buddha family.
To sum up, the Bull Devil King himself has a happy home in the Cuiyun Mountain Basho Cave, the Bull Devil King saw the benefits and forgot his righteousness, left the Iron Fan Princess to go to the Thunder Mountain, and threw himself into the arms of the Jade Faced Fox, when Sun Wukong came with only this Rulai Buddha background team, the Bull Devil King was deeply afraid that the Iron Fan Princess's banana fan was taken away, so he quickly returned to Cuiyun Mountain, began to fight against Sun Wukong with the background of Rulai Buddha, and finally gave in to Rulai Buddha.
It can be seen from this that the Bull Devil King sees profit and forgets righteousness, the most loved is himself, which side is advantageous, he does not really like the Iron Fan Princess, nor does he really like the Jade Fox, but these two people have their own needs, and it is Sun Wukong who exposes the true face of the Bull Devil King.
