Ch’ih Yu is the “god of war” in Chinese myth. He is not only a brave “god of war” but also a great “god of weapon”. Because he was good at fighting as well as making excellent weapon. Although he was defeated by Huong Di on the Cholu Battle, people worship him as a hero increasing day by day. And furthermore people named the star and the cloud after his named. Nowadays there are many excavations of jade blade and Tao Tei of bronze wore from Shang to Zhou, which also have the main excavations of Ch’ih Yu in Chinese myth. Then why a failure in war could be called “god of war” and “god of weapon” ? Why he became the capital patterns of ancient Chinese sculptures? It would be discussed in this paper.
