What does the idiom "fire in July" mean?

The "fire" of "July filariasis" actually refers to Mars, which is Antares. "Flow" means decline and decline. Every year in the summer calendar, at dusk in May, the heart stays in the middle of the sky, and after June, it gradually goes west. At this time, the summer heat began to decline, so it was called "filariasis", which means that "Big Mars" gradually moved westward and fell. It's July in the lunar calendar, and it's getting colder and colder.

"July filariasis" does not mean that the weather is too hot, on the contrary, it actually means that the weather is getting colder and colder. This idiom comes from July.

This poem reflects the great disparity between the life of the ancient peasants and the aristocratic ruling class: the peasants worked all the year round, but they did not have enough to eat and wear warm clothes, and lived well, while the ruling class lived in a house that was cold and heatstroke-proof, ate wine and meat, wore exquisite and beautiful clothes, and enjoyed banquets and sacrifices when they were idle, hoping that God would bless them to live a long life.
