Gander and who discovered the law of five-star emergence

Gander and Shi Shen discovered the law of five-star emergence.

1, Gander

Gan Desheng died in Qi during the Warring States Period. He lived in the middle of the 4th century BC. He was a famous astronomer in the pre-Qin period, the compiler of the oldest catalogue in the world and the earliest discoverer of Ganymede. He is the author of eight volumes of Stars in the Sky and Chronicles of Stars. Later generations combined his astronomical works with the works of Shi Shen into one, and called it Shi Gan Xing Jing, which is the earliest astronomical work in the world. ?

2. Shi Shen

The date of birth and death of the stone god remains to be verified. Shishenfu, also known as Shishenfu and Shishenfu, was an astronomer, astrologer and Kaifeng native of Wei in the middle of the Warring States Period. He was one of the China people who named the crater on the back of the moon after himself. Eight Volumes of Astronomy and Eight Volumes of Stars by Gander are collectively called Shigan Star Classic, which occupies an important position in the history of astronomy in China and the world.

The hottest day of the year is coming to an end.

Out of the day means out of the day, the day is over, and autumn is coming. In the Yuan Dynasty, Dai Li Weng, a bamboo vine, wrote a poem: "Silkworms are urged out when they sleep for one or two hours, and three or four-leaf seedlings are still worried about the wind", which is a record of eclosion in ancient poetry. Take an ultra-thin coat or scarf shawl when you go out against the wind. It will be cool and windproof in the morning and evening and after the rain. Pay attention to keep warm when sleeping, protect your waist, abdomen and back when sleeping, and sleep less on summer mats to avoid being stiff due to cold.
