What does Yuan Shoucheng's ingenious and selfless song mean by Lao Wang Long's clumsy plan to break dogma?

This is the story in The Journey to the West, the ninth time: "Yuan Shoucheng's wonderful and selfless song".

Synopsis: Because Yuan Shoucheng can calculate the location of Jinghe Aquarium, King Jinghe was very angry and scared, so he went to Chang 'an to find trouble with Yuan Shoucheng and asked him to calculate the time of rain. Yuan Shoucheng was right.

King Jinghe had a very stupid idea, and changed the hours of rain privately to prove that Yuan was "not allowed" and smashed his stall. As a result, the Jade Emperor knew that the Dragon King had changed the time privately and violated the dogma, and was beheaded by Wei Zhi in his dream.

The origin of the door god

At the second watch of the night, the king of Tang heard the sound of sadness outside the palace gate. When he was frightened, the king of Tang fell asleep in a daze. Unexpectedly, the headless king of Jinghe in his dream, carrying a bloody head, rushed to the Tang King, grabbed his hand and called him by his first name: "Li Shimin! Give me back my life Give me back my life Thanks to your promise to save me or not, how can you help that Wei Zhi hunt me down? Come out! Reason with me to go to the king of hell! "

The king of Tang was speechless and sweaty. He can't get rid of the entanglement of the dragon king. He shouted a ghost before he woke up from his dream. At this point, for several days in a row, the king of Tang was disturbed by the ghost of the Dragon King every night and fell ill, with weak pulse. King Tang was seriously ill. Wei Gong Weichi Gong and lord protector Qin came to see him and found him outside the palace gate. At night, they throw bricks and tiles and call for ghosts.

The second general comforted the king of Tang. Qin said, "Your Majesty, relax. Tonight I will guard the palace gate with Jingde to see what's sneaking around. " Tang Wang allowed the play, and the two thanked him. In the evening, the two generals were all dressed up, wearing golden helmets and silver armor, commanding and commanding, holding knives and axes to guard outside the palace gate. After a calm night, the king of Tang slept soundly.

Although guarded by two generals, the palace was quiet for a few days, but after all, the king of Tang could not bear the hard work of the two generals, which made them miserable day and night, so he found painters, painted the true faces of Weichi Gong and Qin on the door of the palace, and the front door was free at night. The prestige and appearance of the two generals have become the door gods of the people.

First, King Jinghe begged Emperor Taizong not to let Wei Zhi behead him, but when Emperor Taizong was playing chess with Wei Zhi, Wei Zhi beheaded King Jinghe in his dream, so later King Jinghe expressed his dream to Emperor Taizong, which led to Emperor Taizong being scared into the underworld, but he was resurrected before his birthday. Later, he promoted Buddhism, but the Buddhist scriptures were incomplete, and later he went to the Western Heaven to learn from them.
