Is "May Day" and "Summer Solstice" not picking cotton a proverb or a motto?

It is a proverb that the May Festival is long and cotton is not harvested on the summer solstice.

The ears of wheat in the Yellow River basin began to grow. The fifth day of the fifth lunar month-Dragon Boat Festival is roughly in this period. The summer solstice is the longest sunshine day in the northern hemisphere. At this time, the local summer is coming, so you don't have to wear cotton-padded clothes all day long.

Proverbs are concise phrases widely circulated among the people, which mostly reflect the practical experience of working people and are generally passed down from mouth to mouth. Most of them are easy-to-understand spoken short sentences or rhymes.

Motto refers to a concise statement that can be used as people's code of conduct, the essence of people's wit, the wisdom gathered by all people, and the magic weapon that guides life to success and always inspires life to keep forging ahead.
