What constellation does July filariasis refer to?

Fire in July, clothes in September.

Literally, the "fire in July" can be easily understood as the scorching sun in July, and the air is like a flame, which makes people suffer in the heat. In fact, this understanding is wrong. This idiom belongs to misinformation and misuse in most cases.

"July is full of fire" was originally a poem in the Book of Songs: July is full of fire, and clothes are given in September. The general idea is that whenever a star named "fire" appears in the western sky at dusk in July of the lunar calendar, the summer heat will begin to fade, and it will be cold in September, so you should wear more clothes. What needs to be pointed out here is that this star named "Fire" is not Mars, but three stars in Scorpio in modern astronomy, belonging to the fifth night of Eastern Airlines Hotel. "Six" means moving down. By the evening of July in the lunar calendar, it has moved to the western sky, so it is called "July Fire".
