The joke of eating moon cakes on Mid-Autumn Festival is that the old father-in-law takes an examination of his son-in-law and asks him to write poems. One of them is "all is silent"

Mid-Autumn Festival, 3 sons-in-law accompany their parents-in-law to enjoy the moon! Bullying the old 3 honestly asks everyone to write a poem according to the situation at that time! Boss: The moon in the sky is round, and it is less than half on the fifteenth day of the first month. The stars are in a mess and the dark clouds are silent! Old 2: The moon cakes on the plate are round. Bite a little, sesame seeds are in a mess, and your stomach is quiet! Old 3: My parents-in-law turned around, one died and the whole family cried. They're all dead. Quiet!
