What do you think is the best inheritance of Chinese civilization for five thousand years?

Chinese civilization draws eight diagrams from Fu, with 0 and 1 representing Yin and Yang, with Yin being 0 and Yang being 1. Draw gossip, know the formation of spring, summer and autumn through the ups and downs of yin and yang, and infer the twenty-four solar terms. Used in agricultural production, it created the earliest square characters "Heaven, Earth, Water, Volcano, Zefenglei". It opened a precedent for human beings to understand nature and use it for the benefit of mankind. Fu culture was passed down unconsciously. People are engaged in agricultural production with the words in Fu and the law of Yin and Yang every day, but they have long forgotten its cultural origin. The best inheritance is that the culture of creating characters with natural phenomena initiated by Fu is never out of date and is passed down imperceptibly. This is the best inheritance.
