The names of the characters in The Journey to the West are all related to dreams.

The Journey to the West's dream-related figure is named Wei Zhi. Wei Zhi, the prime minister of the Tang Dynasty, beheaded King Jinghe in his dream. The novel The Journey to the West records Wei Zhi's dream of beheading the dragon king. The story goes like this: During the Zhenguan period, Chang 'an, Tang Dou suffered from drought for years, and the bare land was thousands of miles away, so it was useless for ordinary people to beg for rain every day. The King of Jinghe made a bet with the fortune teller. The fortune teller concluded that it would rain at three o'clock the next day, three o'clock in the city and seven o'clock outside the city. King Jinghe doesn't believe it. Later, it was clearly written on the jade emperor's decree: the clouds cleared at dawn, the thunder rumbled at dusk, it rained at noon and didn't stop at noon. In order to win the bet, he tampered with Colleen Chan privately, changing three o'clock in the city to seven o'clock and seven o'clock outside the city to three o'clock. As a result, heavy rain fell in the city, drowning many Li people, and only three points fell outside the city. The fields are still dry, the seedlings are dead and the crops are poor. The Dragon King scattered rain at will, breaking the dogma. The Jade Emperor wanted to behead him, so he sent Wei Zhi to supervise and beheaded the old dragon at 3 noon. The day before, Lao Long asked Li Shimin to intercede for him, and Li Shimin readily agreed. The next day, Li Shimin announced Wei Zhi to North Korea and left Wei Zhi to play Go with him. It's time for execution, and Wei Zhi can't escape. Finally, he fell asleep at his desk.
