What are the signs of thunder and rain on the first day of the seventh lunar month?

As the saying goes, "It thundered in early July, and it was windy on 14th July". This is easier to understand. It doesn't rain on the first day of July, and the autumn wind is bleak on July 14!

As the saying goes, "the first day of July, the wind and rain are twenty-four." The proverb "move first": in fact, it means that the rain appears and the rain falls. "Twenty-four" is a quantifier, which means July and 24 days of wind and rain. It seems that there is more rain, which is accompanied by rain almost every day.

As the saying goes, when it rains on the first day of July, it will rain for more than 20 days on the earth, which is a sign of rainy days.
