Datong is one of the 24 famous historical and cultural cities in China due to its ever prosperous history. With a history of over 2400 years, it was the capital of Northern Wei (386~534) for 96 years, and the 'support capital' of Liao (916~1125) and Jin (1115~1234). It was the political, economic and military center of ancient North China, which attracted many people from various nations for trade or business. These prosperous days left the city with a series of splendid historic and cultural relics like the Yungang Grottoes and Hanging Monastery. Most of them are the integration of minorities' cultural and Han culture.
