What's clean about choosing a day to fight?

The antonym of a good day is a good day. It means a good time, an auspicious day, that is, an auspicious idea, and is often used to address a suitable wedding day.

Although this statement has superstitious elements, it is undeniable that it has become a custom. This word comes from the original sentence of Chu Quyuan's Nine Songs of the Eastern Emperor Taiyi in the Warring States Period: "Good day, Mu will be happy with God." The moral is: auspicious days are beautiful moments, respectful worship of God and solemn worship.
