Unfortunately, due to evil. Shanqing's ruler is not a treasure, but an inch of shade is a game.

Explain that disaster is the result of evil, and blessing is the return of charity. A foot-long jade is not a real treasure, but even a moment is worth cherishing.

[Note] Misfortune and blessing: The language "Yikun Classical Chinese": "If you accumulate goodness, you must have Qing Yu; If you are poor and weak, there must be more than one. "
