Which country first discovered (invented) the four seasons of spring, summer, autumn and winter?
Autumn dew, autumn frost, little snow in winter and cold in winter. China was founded by agriculture since ancient times, and the accuracy of the calendar directly affects the national economy and people's livelihood. Therefore, emperors of all dynasties attached great importance to the revision of calendars. Before the Warring States Period, the calendars used by Huangdi, Zhuan Xu, Xia, Yin, Zhou and Lu dynasties were all "four seasons calendars". Among them, the calendars of Huangdi, Zhou and Lu are based on the moon, that is, the mid-winter month (November of the lunar calendar) is the first year. In the calendar of the Yin Dynasty, the ugly moon was built, that is, the first year was the winter moon (December of the lunar calendar). In the Xia calendar, the month was built in Yin, that is, the first year of Meng Chunyue (the first month of the lunar calendar). In Zhuan Xu's calendar, the moon was built on the sea, that is, in the first year of Meng Dongyue (October of the lunar calendar). By the time of Emperor Wu of the Han Dynasty, there was already a deviation between the calendar and the astronomical phenomena. The description of this period in Hanshu Falizhi is: "See the new moon, the strings are full of hope." Emperor Wu of the Han Dynasty ordered Sima Qian, Luo, Liu and others to change the Zhuan Xu calendar of the Qin Dynasty and set up a new calendar, still taking the month in the summer calendar as the beginning of the year and incorporating the 24 solar terms into the calendar. This calendar has been used for more than two thousand years, and it was only after the Republic of China that it was changed to the solar calendar.
Although Greece has something similar, it is the similarity between the two civilizations, but the order is different. There is no such thing as plagiarism.
