What is the allusion of "Fire is flowing in July, but August is still young"?

The flow of fire in July comes from the "Book of Songs" and refers to the westward movement of the big Mars and the cooler weather.

The weather starts to cool down from the hottest month in the lunar calendar, but it is the second hottest month of the year. So July is still unbearably hot.

"July Fire" is the transition from extremely hot weather to cooler weather, which means the weather starts to turn cooler from the hottest.

Allusions

Three thousand years ago, there was a country called Bin (bīn) under King Cheng of Zhou Dynasty, which was located in Bin County, Shaanxi Province today. Bin State was the birthplace of Zhou nationality's agricultural culture long ago. At that time, the calendar was not yet perfect, and farming activities relied on stargazing. Every year at the end of summer, a red star named Fire, Alpha Scorpius, appears in the southern sky. Based on ancestral observation experience, farmers know that summer is over, autumn is here, and the busiest autumn harvest season of the year has arrived.

A few days passed quickly, and at the same time on Qiu Xi, the farmer looked at the southern sky again and found that the big fire had moved westward and dropped compared with a few days ago. A few days later, it moved westward and fell even more. At the same moment a month later, looking at the southern sky, the fire had moved to the western horizon. It was too low, obscured by clouds and mist, covered by the mountains, and could not be seen. Dear readers, this process is called "Flowing Fire in July". There is only one solution, not two. The water bows its head and is said to flow. The fire is also flowing westward. Fire has a unique connotation here, and its meaning is special. It refers specifically to the star Alpha in Scorpio, which is called Antares in ancient Chinese astronomy. It is definitely not the fire of "the red sun is burning like a fire". Just as the name implies, it will make a joke.

"August is still young", these four words as a whole word or sentence have not appeared in ancient books, and there is no source. If you have to explain it, according to the literal meaning, it is " August is not over yet”. According to the lunar calendar, July and August in ancient times are now August, September or even October. Therefore, the "Flowing Fire" in July means that the sun begins to lose its temperature and the flames are lost, while the "Weiyang" in August means that the nights are gradually getting longer, and "Weiyang" means that the nights are slowly getting longer. meaning.
