“Han-shu Wu-xing-zhi” is the summary of thought on calamity of Western Han Dynasty, whose structure is based on the “Five-element”, “Five-incident” and “Divine Sovereignty” of “Shang-shu Hon-fan”. But the stated examples from it rely mainly on the calamity written in 242 years of “Chunqiu Studies” and 211 years of Western Han Dynasty, and the calamity of “Chunqiu Studies” all quotes from the sayings of Dong Zhong-shu, Liu Xiang and Liu Xin. This article discusses the sayings evolved from the calamity in “Chunqiu Studies”, the interpretation and application of history at all times among them, and compares and analyzes with the contents related to the three Commentaries of “Chunqiu Studies”. We find out that the interpretation of Dong Zhong-shu, Liu Xiang and Liu Xin between the three Commentaries of “Chunqiu Studies” are entirely different. They interpreted the calamity in “Chunqiu Studies” with the angle of the interaction between mankind and universe, and used the authority of “Heaven’s warning” and “Scriptures” which borought influence on political affair at that time. However, this kind of intention of yielding to the subjective purpose that they wanted to use ancient history to satirize the present had brought negative influence on the explanation of the calamity in “Chunqiu Studies” unavoidably. What they had interpreted was ambiguous and different, and it makes people to be at a loss as to what to do and easy to be used by certain people, which caused a result that the “earthly desire” flows by beans of the “heavenly heart”.
