What are the ancient ideologies or customs that are worth preserving to this day?

An organic composite of all material and spiritual cultural phenomena such as customs, morals, ideas, arts, institutions, and lifestyles inherited from history. The traditional culture of any nation is formed and developed in the course of history, with the evolution of history and the continuation of generations, have their specific connotation and dominant basic spirit. Traditional culture contains tangible material culture, but more in the intangible spiritual culture, embodied in people's lifestyles, customs, psychological characteristics, aesthetic interests, values, internalized, accumulated, penetrated in the psychological depths of members of each generation of society. Traditional culture has four major characteristics: First, the old and the new are blended.

Traditional culture is something that has been developed in the past and is the result of the intermingling of the past and the present, infiltrating the new ideas and new blood of each era, and is not the original creation of the ancients. The second is relative stability. Undeniably, traditional culture is in the dynamic process of constantly absorbing new content and formation, but it is rooted in their own national soil in the steady state of things, there is a relative unchanged side, can transcend the times and long continuity. Any cultural phenomenon that does not have such stability will be eliminated by history with the passage of time and will not be recognized as tradition. Third, ethics. Although the ethical concepts of various countries and nations have different standards and forms of expression, this is the strength and reason for the continuation of traditional culture, which is quenched by the recognition of social and moral concepts outside the realm of compulsory law. Fourth, the broad social nature. Traditional culture is neither the viewpoint of the sage, nor the ideological tendency of a few people, it reflects and represents the overall consciousness and general tendency of a nation and society.

In conjunction with the above, we can try to make a crude summary of traditional Chinese thought. It refers to the spiritual and cultural phenomena formed in the atmosphere of Shi, Confucianism, Taoism and the Hundred Schools of Thought as the dominant culture in the course of Chinese history at all levels of the whole society, which are reflected in customs, morals, culture, art, institutions and life style. 1. In terms of thought and culture, of course, Confucius, Lao, Zhuang and other scholars as the first, one is due to the advanced thought of these thinkers at that time, on the other hand, is out of the ruler for the people's thinking of the "management" of the need. The influence of the later Cheng-Zhu rationalism was also quite extensive. It is beyond my ability and interest to summarize each school of thought. 2. In terms of morality and ethics, Confucianism seems to dominate, and there are so many allusions to it that I do not need to repeat them. It calls for loyalty, filial piety, benevolence and righteousness. Guan Zhong said, "propriety, righteousness, honesty and shame are the four dimensions of a nation", which has been regarded as a sacred saying throughout the ages. 3. In terms of social system, "three streams and nine classes" and "three religions and nine streams". It varies from dynasty to dynasty. But the social structure must be in the shape of a pyramid, with the "Son of Heaven" standing on top of the people. 4. Lifestyle issues, clothing, food, housing and transportation is not a reflection.
