What is Longxing in Zhouyi? Can there be some astronomical information such as pictures?

Long Xing is the big Mars in July; The summer calendar is full of fire in July, and the weather begins to turn cold.

"Fire" is the name of this star. According to the traditional division of China's "three walls and twenty-eight lodges", the "Fire" star belongs to Antares, named after its red color. According to the western constellation, it belongs to Scorpio and is a red Supergiant star. "Fire" is bright. It is listed in the "brightest star list" in the volume of "Chinese Encyclopedia Astronomy", and only 2 1 star (some are binary stars) is received.

In the poem "July", the sentence after "July filariasis" is "clothes are given in September", which means that in September of the summer calendar, the work of sewing winter clothes will be handed over to women.

In ancient times when the calendar was not complete, the bright "fire" star became the basis for people to observe the sky, judge the season and determine the farming season. Therefore, Gu, a scholar in the late Ming and early Qing Dynasties, said in the Record of Japanese Knowledge: "Anyone who knows astronomy has more than three generations. There is a fire in July, and the words of farmers are also. "

Note: Mars, the long star, is a star, not the planet Mars (fluorescent star) in the solar system.
