王充
Wang's reference to Gongyan Gao's (i.e. Gongyan Zhuan's) commentary perhaps demonstrates that Gongyan's work, compiled in the 2nd century BC, explored the topic of the hydrological cycle long before Wang wrote about the process. The British biochemist, historian, and sinologist Joseph Needham asserts that: "As to the seasonal lunar and stellar connections, the thought of Wang Chong (about 83 AD) is that in some way or other the cyclical behavior of the qi on earth, where water is distilled into mountain clouds, is correlated with the behavior of the qi in the heavens, which brings the moon near to the Hyades at certain times." Thus, Wang Chong was uniting classical Chinese thought with radically modern ways of scientific thinking in his day.
