Communication of spiritual civilization The Analects of Confucius, Shang Shu, War State Policy, Ninety-Nine Numbers and other works were introduced to the Western Regions through the Silk Road during the Han Dynasty, which shows the influence of the Han Dynasty on the Western regions. Culture is the general name of material culture and spiritual culture in the middle and lower reaches of the Yellow River, which is the mother and backbone of Chinese culture. Culture as the core, with the vast middle and lower reaches of the Yellow River as the hinterland, layer by layer radiates outward, the influence extends overseas. The region is the cradle of Chinese civilization, and its culture is an important source and core component of Chinese culture. In ancient times, the region was not only the birthplace of China's political economy, but also the mainstream culture and dominant culture. It must be noted that the regionalism of the culture is obvious and different from other regional cultures, and its most noteworthy feature is the direct correlation with the formation of Chinese culture. Due to the siltation of the Yellow River and many convenient natural conditions such as climate, a developed agricultural civilization has been formed here since ancient times, and it has crossed the "threshold of civilization" first among all regions. The culture derived from this civilization provided the basic model for the social and political system, cultural etiquette and ordinances of later China. At the same time, the reason why culture occupies an important position in the overall pattern of Chinese culture lies in its powerful radiation force.
