In the "Great Unity" section, ancient astronomical charts on the exhibition hall's ceiling capture the ancient Chinese belief in the unity of heaven and humanity. The Pillar of Converging Thought (the Jisi pillar) is at the front, symbolizing that China's charming culture is the convergence of the cultures of China's ethnic groups. A petal-shaped ancient book wall is in the back.

In the "Great Integration" section, the gauze curtain displays a traffic map of the Western Regions in ancient times, depicting the prosperous scene of the ancient Silk Road. Some major traffic corridors for ethnic groups lie on the ground. Through these corridors, people from different ethnic groups migrated and conducted business. The corridors also witnessed the exchanges and integration of ethnic groups.
