One of the characteristics of Yuan Zaju
At the end of each fold of a drama, two, four or eight lines are used to summarize the whole drama, which is called "getting to the point".
The closing poem at the end of each zaju is used to summarize the ideological content of the whole drama and point out the title of the drama.
For example, the poem at the end of Dou E's injustice is "Insist on fair and honest visits to the law and feel Dou E's injustice"
