Qingming related knowledge

The related knowledge of Qingming is as follows:

Qingming is one of the twenty-four solar terms and the fifth solar term in spring. It will clear up when the sun reaches 15. Tomb-Sweeping Day was named after "The Riverside Scene at Qingming Festival shows everything". Qingming is a solar term that reflects the phenological changes in nature. At this time, the sun is shining, plants are sprouting, flowers are in full bloom, and nature presents a vibrant scene. In the south of China, it has become a clear and beautiful image at this time; It began to snow in the north, the temperature rose, and spring blossomed.

Qingming is a vibrant season, and it is also the decline season of Yin Qi. The earth presents the image of spring and tranquility, which is a good opportunity to go for a spring outing in the suburbs and offer sacrifices to graves. Qingming has both natural and humanistic connotations, which is both a natural solar term and a traditional festival. Tomb-Sweeping Day is rich in festivals and customs. Grave-sweeping and outing are two major themes in Tomb-Sweeping Day.

The age of early observation of images and timing was determined according to the changes of stars. The Big Dipper appears in different directions in the sky in different seasons and at different times at night, so the ancients determined its age according to the direction pointed by bucket handle when he fainted for the first time. Beidou became the maker of the order of heaven and earth. Spring, summer, autumn harvest and winter storage all seem to follow the direction of Beidou.

The "Twenty-four solar terms" were originally determined by the direction of the top of the bucket handle of the Big Dipper. The bucket handle starts from the "female" position and then rotates clockwise. When bucket handle points to the "second position", it is the spirit of Qingming. ?
