When we analyze the structures of the mythological Goddess in "Kao-tung Fu" from three different editions, and try to explain the functional meanings of her power of charming and her willing to betroth herself, we find that the keypoint is Yaogi's death in unmarried status. A girl died in early age would be considered as unnatural. She would not be treated as traditonal religion ritual did. In the ancient China, especially in Han's people society where predmoinated the partiachy, a girl died in immature age unnaturally would mean a restless soul without any reliance in the secular world. The legend of mythological unmarried Goddess in "Kao-tung Fu" is a reflection of the structure meanings about "permanent and non-permanent" in chinese culture. Tinuh (帝女), looks for a metamorphose in yao (草) to continue her unnatural life and thus to relieve the complain and grievance that her short unmarried life had left. Her voluntary betroth to the King of Tzu-hwai, can be considered as an aspiration to realize a marital life. The reason thak King Tzu-hwai have enshrined Tinuh is the symbol to keep a pledge to pray and repay between the human and gods, furthermore this acceptance could console the soul of the early dead Princess and givher comfort reliance. The essential topic of "Kao-tung Fu" just reflects the collective psychology and the deep aspiration in chinese culture:Women have to be betrothed.
