Abstract: Offering sacrifice to ancestors, a process to find the roots of our family, nation, history and culture, is very important to our self-identity either as an individual or an ethnic group. The ancient "Qiang" was a general term for the ethnic groups who lived in northwest China. Today, the Qiang people living in the upper reaches of the Minjiang River in northwestern Sichuan are descendants of the ancient "Qiang". Nowadays, the tribal consciousness of ancestors of Erma people is clearly shown in the building clusters named "China Qiang City" in Maoxian which is the center for Qiang culture. Starting from the ancestral sacrifice of Yuan Hao Memorial Halls in the Qiang temple, based on the field investigation in northwest Sichuan Qiang area and other things about Qiang society, history and culture, this paper explores in depth the problem of ethnic psychology and cultural identity, which is important for us to understand Chinese Qiang and its culture in the present context.
