Was the twenty-four solar terms created by Luo, an astronomer in the Western Han Dynasty?

Twenty-four solar terms, a supplementary calendar, were established in the pre-Qin period in China and completely established in the Han Dynasty to guide farming. It is a knowledge system formed by observing the movement of the sun in a year and understanding the changing laws of the four seasons, climate and phenology in a year. It divides the sun's annual trajectory into 24 equal parts, and each equal part is a solar term, starting from beginning of spring and ending with severe cold. It is not only a time standard promulgated by successive governments, but also a compass to guide agricultural production. The compass for predicting cold, warm, rainy and snowy weather in daily life is the crystallization of the long-term experience and wisdom of the working people of the Han nationality.
