Ask the story of three folk women!

One day, a rich man called three sons-in-law to celebrate his birthday. Just as he was eating, the rich man suddenly came and said with interest. I will give twelve taels of silver to anyone who can write a poem that includes four words: big, small, much and little. The three sons-in-law readily agreed.

The eldest son-in-law saw the fan in the rich man's hand shaking and began to say; Father-in-law's style is really strange. It is big when it is opened and small when it is merged. Use more in summer and less in winter.

The rich man listened to the applause and gave the eldest son-in-law twelve taels of silver.

Not to be outdone, the second son-in-law said, I wrote a poem on my father-in-law's clothes: my father-in-law's clothes are really good. When you put them on, they are big, but when you take them off, they are small. I wear more during the day and less at night.

Hearing this, the rich man gave his second son-in-law twelve taels of silver.

Now it's the third son-in-law's turn, but the third son-in-law is a plowman, not a scholar like the eldest son-in-law and the second son-in-law, and he can't figure it out after thinking for a long time.

Suddenly I had a brainwave and said to the rich man, how is my mother-in-law?

Hearing this, the rich man thought it was a good idea. They all talk about death, and you talk about life. If you can say it, I'll give you twenty taels of silver.

The third son-in-law sang happily: how nice the mother-in-law is! Big in front of me, small in front of my father-in-law, others use more, and my father-in-law uses less.
