In front of the Water Curtain Cave in Huaguo Mountain, thousands of golden lights pour down from the sky, illuminating the mountains and plains with golden light. The spring water hangs upside down from the top of the cliff, falls into the deep pool and stirs up thousands of piles of broken jade; the branches of the ancient trees stretch out, covered with peaches, apricots and exotic fruits, and the fragrance permeates the countryside for ten miles. From time to time, monkeys' cries of joy can be heard from the mountains, mixed with the clanging sounds of swords, guns, swords and halberds - the Monkey King Sun Wukong, who has returned from becoming a Buddha, is lying on the highest marble stone, half-squinting his eyes, enjoying the leisure he has not experienced in three thousand years.
