"Lingpai Mystery" was said that a couple ate their head off, loafing around and doing nothing, living from hand to mouth, so they acted as dead man to get money by fraud. The libretto of the hero was humorous when he acted as a fortune-teller, from which we can have insight into popularization of Lantern Opera in Northern Sichuan. The leading characters in this drama were not heroes, not the knights, but the villains, should be philistines. The actor Shua Erge was a famous "lazy man", the heroine Shua Ersao was a famous "greedy woman". Because the couple ate their head off, living a hard life, so they had to cheat.

The play with such villains as heroes is not only fresh but also popular, not only closing to people's life, but also proving straight features of Lantern Opera in Northern Sichuan. The couple’s bad habits were described with humorous local dialect dialogue and aria at the beginning: one was lazy, another was greedy; one liked to eat jelly, another liked to eat Tangyuan, what to do without anything to eat and drink? The couple got together to deceive. This couple shared out the work and helped one another. Unfortunately, the old couple met the hero and heroine separately when they were saving the poor. Here was used exaggeration and coincidence again, let two crooks with the same means to deceive both old people, finally clever people may be victims of their own cleverness, their lies were easy to see through the elderly, they had to admit his mistakes at last! Repertoire was elaborated with a large number of exaggerations, and language had been processed and refined, so it was valuable to watch.
