What season is filariasis in July?

Filariasis in July refers to the gradual cooling of the weather, which generally describes the arrival of autumn and is easily mistaken for hot weather.

1. July filariasis is an idiom in China, and its pinyin is q and yuè liú hu ǒ, which comes from the Book of Songs and refers to the westward movement of Mars and the cold weather. Can't be used to describe the hot weather.

2. "July" refers to the July of the weekly calendar, "Xia Zheng Yin Jian, Andrew Jian Chou, Zhou Zheng Jian Zi". July in the weekly calendar is September in the summer calendar, that is, September in the lunar calendar today, which is roughly equivalent to October in the Gregorian calendar. "Flow" means moving and falling.

3. "Fire", the name of the star, refers to Mars, also known as Antares. Every year in the summer calendar, at dusk in May, the heart stays in the sky and gradually goes west after June. The heat in summer began to subside. So it is called "filariasis". The ancients found that Mars gradually moved westward and the weather began to get cold when it set.

The "fire" referred to here is not the weather like fire, but the name of a star, which is Scorpio α. It is the brightest star in Scorpio, emitting lux light, so ancient astronomy in China called it "fire" star, also called antares.
