中国古代先民，通过观察云和风的变化以及天象、星象和光象的特征等，归纳出一些预报天气变化的规律和方法，由此产生了不少的占候家。春秋末期的孔子是文献记载的最早的占候家。汉代的京房、任文公、公沙穆，三国的管辂，北齐的吴遵世、张子信，唐代的裴行俭和宋代的沈括、武桢等都是优秀的占候家。 Ancient Chinese ancestors, by observing the changes of clouds and winds and the features of celestial bodies, astronomical phenomena and light phenomena, summed up some laws and methods of forecasting the weather changes, resulting in a lot of occupation. Confucius in the late Spring and Autumn Period was the earliest occupation of literature. In the Han Dynasty, Jingfang, Ren Wengong, Gongshamu and the Three Kingdoms, Wu Zunshi and Zhang Zixin in the Northern Qi Dynasty, Pei Hangjian in the Tang Dynasty and Shen Kuo and Wu Zhen in the Song Dynasty were excellent occupiers.
