There was a husband who was famous for his thriftiness.
One day, when he came home from work and sat down to eat, he saw that the stir-fried vegetables were very delicious and curiously asked his wife:
- Why are the stir-fried vegetables so delicious today?
The wife heard that and happily showed off to her husband:
- This morning, two people bought a piece of pork fat together and came to our house to borrow a knife to cut it up and share it. When I cooked the rice, I washed the knife in the pan, that's why the vegetables were so delicious.
The husband was angry and slapped his wife, then shouted:
- How stupid! Why didn't you wash it in a jar of water so you could eat it for a few days!
The wife was so upset that she covered her face and ran to her parents-in-law's house to tell her husband's story, but unexpectedly, her father-in-law shouted:
- That's still a light beating. Why didn't you wash it in the well so we could eat it too?
