Needless to say, from the viewpoint of life science, because of the chromosome, ＂god＂ Zhi Ge A-Long can be impossible gestated by＂eagle or condor or dragon eagle＂;people can not be raised by＂dragon＂. At present, with the Yi heroic epic The Zhi Ge A-Long translated into Chinese or in the transmission process of Yi offspring ,＂dit＂in the text has been translated or explainted for＂eagle or hawk＂, which understanding isn’t right completely. What do the＂eagle＂who got PuMonii pregnant and the＂dragon＂who fostered Zhi Ge A-Long growth symbolize？ What cultural meaning does it express to the descendants？ From the perspective of life science ,the paper puts forward the＂Eagle＂is the symbol of male root and＂dragon＂interlinked Chinese cultures is the totem of man in order to make literature better protection, inheritance and interpretation.
