Political system and ethnic integration, Chinese and foreign exchanges: for example, Zhang Qian sent a mission to the Western Regions in the Han Dynasty and introduced technology and products from the Western Regions; The national policy of openness, tolerance and eclecticism in the Tang Dynasty and the policies at home and abroad made Chang 'an, Tang Dou an international metropolis. Jian Zhen traveled to Japan, and Xuanzang learned from Tianzhu, which played an important role in spreading culture. The mercantilist policy of Song Dynasty and the appearance of paper money further promoted economic development, and overseas trade was unprecedentedly prosperous. In the Ming Dynasty, Zheng He went to the Western Seas and had political, economic and cultural exchanges with Asian and African countries, which introduced rich products and promoted the development of shipbuilding and navigation.

The country is rich and strong: the politics is clear, the people's hearts are stable, the society is harmonious, and long-term stability: for example, the rule of Wenjing, Huang Kai, Zhenguan, Kaiyuan and Kanggan, only a peaceful and harmonious country, a unified multi-ethnic country and stable centralization can give a good environment for economic development.
