A poem indicating that there is no money for the New Year.

I'm afraid I'll be shy when I'm empty, so I saved a dollar to watch it. Judging from Du Fu's five-character poems, how poor Du Fu really is. Every day, he feeds on cypress trees. In winter, the well water freezes and the fire can't be started. There is no winter clothes to keep out the cold at night. Leave a penny to study, which means that no matter how poor you are, you should leave a penny for self-defense, which means that you are too poor to face your ancestors when you die.
