The New Legend of Budai Monk is based on the story of Maitreya Buddha circulated among the people. The whole play is divided into several units, such as the opening of the lotus, the calamity of the heart, the fate of the immortal couple, and the calamity of the relics, telling the story of Maitreya Buddha's reincarnation and cultivation in the world. Budai Monk's previous life, Maitreya Buddha, was unruly by nature, despised all the rules and regulations, and especially disliked the stale dogmas of the heavenly court. He was sent to the mortal world by the Buddha to practice because he bumped into the Jade Emperor. Budai Monk eliminates evil and promotes good, uses his wisdom to fight wits and courage with the evil forces in the world, saves the people from suffering, and is respected and loved by the people. The sentence "A big belly can tolerate things that are difficult to tolerate in the world; open your mouth and laugh, laugh at the ridiculous people in the world" is a true portrayal of Budai Monk.
