Journey to the West: What Does It Mean That a Monkey Is Coming from the Opposite Side?

This book is also called "Master Bodhi: This is My Worst Class of Students" I fell asleep in class and woke up to find that I had traveled through time. Jiang Li thought that he had traveled back to ancient times and was taken to the mountain to practice by an old Taoist priest with an immortal spirit. The old Taoist taught him to sleep, and the old Taoist taught him the exercises and he fell asleep again while watching them. Three years later, the old Taoist was so angry that his beard became crooked. He kicked him down the mountain and threw a whisk and a bodhi seed at him: "If anything happens, I'll find your senior brother." Jiang Li: "Who is my senior brother? Where can I become an official?" The old man said: "He will come to you by himself." After going down the mountain, Goldfinger arrived - one hundred thousand fully armored elites, 20,000 fully equipped cavalry, and an unlimited supply of food and grass. Jiang Li: With this configuration, even if it's Liu Xiu, I'd bet on a CD! So he led his army towards Chang'an in a mighty manner, crushing them all the way, and Li Shimin's face turned green. Then a monkey with a hairy face and a thunderous mouth fell from the sky. "That man surnamed Jiang, come out to see my grandson!" Jiang Li:? ? ? What is this? Is this Journey to the West?
