Inventor of the Twenty-four Solar Terms-Di Ku

(2275-2 176), born in Ji, Mingjun (now Gaoxin Town, Suiyang District, Shangqiu City, Henan Province), the great-grandson of the Yellow Emperor, was one of the five emperors. Di Ku reigned for 70 years, and his life expectancy was 105 years. After his death, the mausoleum of the First Qin Emperor was built in Gaoxin (now Gaoxin Town, Suiyang District, Shangqiu City, Henan Province).

Legend has it that before Di Ku, although people had the concept of four seasons, they only worked at sunrise and rested at sunset. There is no scientific time sequence for engaging in agricultural animal husbandry, which seriously restricts the development of agriculture and the improvement of people's quality of life. Therefore, Di Ku scientifically explored the laws of astronomical phenomena and phenological changes, divided four seasons, and invented twenty-four solar terms to guide people to engage in agricultural and animal husbandry activities according to seasons, which greatly promoted the development of social productive forces.

? Di Ku era can be said to be a peaceful and prosperous era in ancient times. His general plan of governing the country is: first, to love the people, and second, to benefit the people, emphasizing honesty and benevolence in politics. Di Ku is especially famous for the honesty of its people. Legend has it that an old woman of Gao Xin's family lives in the royal family. She dreamed that the golden dog was born in the lower world. When she woke up, she felt an earache. She called a famous doctor to treat a 13-inch-long golden worm, which was stored in a jade plate covered with a leaf. It is an inch long every day, 12 feet long. Shaped like a phoenix, it is called Lin Gou and Pan Hu. It has a beautiful body pattern and 24 yellow spots on its head. At that time, Di Ku sent a letter asking for a virtuous man, suggesting that whoever could cut off Wang Fan's head would marry Yincui gorge, the daughter of Di Ku. After Pan Hu announced the list, he immediately went to the enemy country, was drunk by Wang Fan, bit off his head, and returned to Di Ku. Di Ku wants to dissolve his marriage because he is a dog. After listening to this, Yincui gorge thought that she should not break her word and ask for marriage. So Di Ku agreed to her daughter's request and married Princess Tiger Pan. After marriage, the princess lived in the mountains with Pan Hu, making a living by hunting and farming in the mountains, and became the ancestor of the She nationality.
