What science, technology and culture have ethnic minorities created? Urgent! ! !

The history of China was jointly created by people of all ethnic groups.

Today, China has become a country with a vast territory, rich resources and a large population, which is the result of the common development of people of all ethnic groups. The Han nationality first developed Shaanxi, Gansu and the Central Plains of the Yellow River Basin. Xiongnu, Xianbei, Rouran, Turkic, Uighur and Mongolia successively developed Mongolian areas. The nationalities in the western regions developed the northwest region; Li nationality first developed Hainan Island; Gaoshan nationality first developed Taiwan Province Province; Tibetan ancestor Tubo first developed Tibet; The ancestors of Yi and Bai first developed southwest Yunnan. In addition, in the process of production development, people of all ethnic groups exchanged needed goods and learned from each other, which promoted the economic development and social progress of ancient China. For example, the process of China's ancient economic center moving southward was the development of Jiangnan by Han people and people of all ethnic groups in the south. A large number of farmers in the north moved to the south, which not only brought advanced production tools and technologies, but also supplemented the labor force. With the joint efforts of people of all ethnic groups, Jiangnan began to catch up with the North in the Southern Dynasties and overtook the North in the Southern Song Dynasty, which promoted the economic center of gravity in ancient China to move southward and promoted the economic development and social progress of Jiangnan. And people of all ethnic groups have jointly created splendid culture. For example, the folk song "Chile Song" of Xianbei people should also receive our attention.
