Historically, the basic pattern of China culture is the opposition between the frontier culture represented by nomadic culture and the farming culture in the Central Plains. Among them, nomadic people are popular in riding and shooting, brave and good at fighting, living in the same state as fighting, and integrating into tribal organizations and military organizations, so they have military advantages and show strategic advantages such as "novelty hunting" and attack. However, due to the limitation of natural conditions and the simple mode of production and economic structure, they have to rely on the central plains agricultural economy as a supplement, and even periodically harass and plunder the central plains agricultural areas. Comparatively speaking, the stability of agricultural economy has enabled the Han nationality to develop a high degree of etiquette and music civilization, and the mode of production of changing land has created the spirit of perseverance and defending the country. At the same time, engaging in agriculture means moving from other places and being self-sufficient, thus turning inward to "non-war" and forming a strategic defense tradition. Therefore, the farming culture in Central Plains has strong adaptability and vitality. However, Han culture also has obvious shortcomings, such as being too stable and lacking pioneering spirit, advocating etiquette and neglecting military affairs, so that it is often difficult to gain military advantages in the process of communication with frontier ethnic groups, especially northern nomadic ethnic groups.
