Tomorrow is unlucky every spring, but you have less luck and more money all year round. According to Zhu Yunming's legend, on New Year's Eve, a rich man asked Zhu Zhishan to write Spring Festival couplets. Although Zhu Zhishan is an outstanding scholar, he has long hated the rich man's rampage in the village. So, while writing Spring Festival couplets, I mocked the rich man. When the rich man posted Spring Festival couplets at the gate, all passers-by applauded.

This couplet is good at breaking sentences. If you break sentences after the words "good" and "little", it is a happy Spring Festival couplets. If you pause after the word "spring" and "luck", it will become an unlucky Spring Festival couplets.
