National spirit is a kind of spirit bred by a nation in the long-term historical development. It is a kind of cultural wisdom influenced and integrated by race, descent, life customs, history and culture, philosophy and so on. It can also be said that it is a nation's internal mentality and way of survival. The national spirit is manifested in a nation's moral integrity, tolerance, demeanor and daily friendship. Especially for a nation's calm, enterprising, self-improvement and indomitable spirit and state of mind in adversity. National spirit is also the soul of a nation's life; It is the embodiment of a nation's unique personality; It is the root of a nation's wisdom. The same nation must have the same cultural consciousness, living customs, moral norms, anxiety mentality and philosophical thoughts; Otherwise, ethnic differences will be formed. Therefore, the national spirit is the lifeblood of a nation, the key to national unity and an important hub for national continuity and development. Rites, Datong articles, the Book of Changes, the great idea, the distinction between Yi and Xia in the Spring and Autumn Period and the spirit of kingliness, the pre-Qin Confucian thoughts of benevolence, loyalty, forgiveness and generosity, the broad reality of Taoism, the vigorous efforts of Mohism, Wen Tianxiang's righteous songs and Zhang Zai's Mingxi all constitute the historical and cultural wisdom of our Chinese nation and the national spirit of our Chinese nation. I quote Wang Aijun's "national spirit" from the International Friendship Association.
