The history of Yinzhong is the story of a young and dynamic urban center that emerged from a large-scale industrial project. Unlike China's ancient cities, its development began in the mid-20th century. Today, Yinzhong, officially known as Zhongshan District, is the administrative, political, and economic heart of Liupanshui, around which the entire agglomeration was built.
The city's emergence is inextricably linked to the "Third Front" state program, launched in the 1960s for the industrial development of the country's interior regions. The government decided to develop the rich coal deposits in Guizhou Province, and a new prefecture-level city, Liupanshui, appeared on the map. From the very beginning, Zhongshan District (Yinzhong) was assigned a key role: it was designed as the central hub that would house administrative bodies, residential quarters for engineers and workers, and the main urban infrastructure.
While mines and industrial enterprises were being built in the surrounding areas, Yinzhong rapidly developed as an urban center. It concentrated not only administrative buildings but also key facilities ensuring the life of the entire region. Yinzhong became the main transport hub and commercial core, managing an economy based on coal mining. This earned the entire Liupanshui prefecture the unofficial title of the "coal capital of Southwest China."
The cultural character of Yinzhong is also unique. It was shaped by the influx of specialists and workers from all corners of the country, creating a special atmosphere of a young and multi-ethnic city. Unlike regions with thousands of years of history, Yinzhong is a living monument to the era of industrialization, which today continues to transform, diversifying its economy and becoming an increasingly modern and comfortable city to live in.
