Tian Wen of The Songs of Chu has a fantastic imagination but also has a lot of faults and confusions. That disturbs the structure of the passage and makes it hard to read. The passage can be divided into three parts. Part one is about world's origin, universe structure and genesis mythology. Part two is about the historical stories before the Spring and Autumn period. Part three is about the practical problems of Empire Chu and the surrounding area. The author tries to take the method of history classification and time order to sort out the inner logical order of Tian Wen and make it easy to read.
