This "Xijiang Moon" is an opening poem, which is used by many stand-up crosstalk.
Seen from a distance,
Look at it, it flutters;
Not a gourd, not a gourd,
A rush and a danger in the water;
That one says it's fish belly,
This says urine;
They bet on the river card circle. Listen,
It turned out that the monk was taking a bath.
