In Chinese plays the moral is always prominent.

The villain is punished, virtue is rewarded, while the majority of the plays are historical.

All healthy-minded people will desire to see a play end with virtue rewarded, and vice vanquished.

Those who want it otherwise are unnatural and possess short views of life.

Either in this life or in some other, each receives according to his deserts, and this lesson should always be taught by the play.
