Shu culture is a concept of regional culture, which refers to a long-standing and unique regional culture centered on Chengdu Plain and Minjiang River Basin. Shu culture is essentially an inland agricultural culture.

As early as 4500 years ago, the late Neolithic culture, as the source of Shu culture, had already emerged in Chengdu Plain. This site, first discovered in Baodun Village, Xinjin County, Chengdu, has a unique cultural connotation, which is different from the ancient culture in the neighboring areas at the same time, so it was named "Baodun Culture" in archaeology.

Baodun culture is an archaeological culture in the gestation period of civilization. At that time, domain, as a settlement form with obvious functional signs, mushroomed in the Yellow River and Yangtze River basins. With the emergence and development of cities, civilization began to grow and be born. Baodun site is not only a typical example of the earliest ancient city site in Chengdu Plain during this period, but also a historical witness that Sichuan is about to cross the threshold of civilization.

1. Economic base: rich in materials, abundant in water and pleasant in climate, which created favorable living and working conditions for ethnic groups with various productivity levels and different economic types in ancient times. This is a very suitable area for planting, breeding, fishing, hunting, gathering and other production activities.

2. Favorable terrain: The terrain here is conducive to the stable transition and development of early civilized society. Surrounded by high mountains, the internal rivers and hills crisscross, limiting the invasion of the northern armed forces. Coupled with the complex terrain, it is impossible to have large-scale floods and droughts. The diversity and variability of this environment have prompted people to cultivate the spirit of being smart, diligent, not afraid of obstacles and being good at adapting to local conditions.

3. Geographical location: The geographical location here is conducive to ancient traffic. In the northern part of this area, there is a Hanshui channel that obliquely passes through the northwest plateau and the southeast lowlands. The "Tibetan-Yi Corridor" near Hengduan Mountain area in the west is connected with Gan Qing Plateau, Central Asia and North Asia in the north. To the south, it can be directly in the south, and it can communicate with East and West Asia, South Asia, West Asia and even Europe and Africa.
