Communication between Sichuanese and Sichuanese

From the 4th century BC at the latest, Ba and Shu, located in the Sichuan Basin, had contact with the vassal states of the Central Plains. After Qin extended to Bashu hometown, a large number of immigrants began to move in. Since then, Sichuan and Sichuan have experienced more tragic natural and man-made disasters than other areas in China, and even had the saying that "there is no chaos in the world, chaos first, then chaos". However, no matter how chaotic it is, Sichuan will be reborn and return to the "land of abundance" and become an important town in the southwest. An important factor is that Sichuan's natural conditions are the foundation of the "land of abundance". Sichuan is rich in water resources. Since ancient times, Dujiangyan's gravity irrigation has created Sichuan's "drought depends on people, hunger is not enough." In addition, the climate is mild, the vegetation is dense and the products are rich. Under the conditions of agricultural production, it can be completely self-sufficient. /kloc-after the introduction of American crops such as corn and sweet potato in the 0/6th century, the hills and mountains around the basin were also developed and utilized more, feeding more people. On the other hand, the closed terrain also makes it easier for Sichuan to defend against foreign invasion, maintain relative stability in the war, or become a stable rear area.

Another important factor is immigration. In the early history of Sichuan, Can Cong, Du Yu and other leaders all came from outside the Chengdu Plain, and the excavated Sanxingdui and Jinsha sites partially confirmed the frequent migration three or four thousand years ago. In ancient times, long-distance migration not only enabled immigrants to obtain new production and living resources and find suitable living space, but also was a process of survival of the fittest. Finally, those who can successfully settle down and reproduce in the immigrant areas are physically and intellectually strong. During the Qin Dynasty's destruction of Shu and Six Kingdoms, a large number of immigrants moved in, bringing advanced culture. At the end of the Eastern Han Dynasty, the Central Plains was in chaos, and a large number of immigrants entered Sichuan and Shu, which became the mainstay of Liu Bei's establishment of Shu Han. During the Western Jin Dynasty, a large number of Miao and Han immigrants moved in, which not only established a separatist regime, but also enabled the local economy, culture and population to continue in repeated wars. This kind of history was repeated again and again in the late Tang Dynasty, the Five Dynasties, the late Ming Dynasty and the early Qing Dynasty. After development, settlement and reproduction, immigrants and their descendants love their second hometown and show extraordinary perseverance and great spiritual strength in resisting foreign enemies. The descendants of Hakka immigrants stubbornly maintained their own dialect and clan life. With the increase of population and the expansion of reclamation and development area, Sichuan's economy has recovered rapidly and celebrities have emerged in large numbers. Almost all Sichuan celebrities in modern times are descendants of immigrants. Thanks to the efforts of several generations, Sichuan has developed rapidly, so after experiencing natural disasters and wars, it can still be restored as a "land of abundance" and become one of the most important provinces in China.
