Those years, that city, those people, those things
The rise and fall of Huaying
It is in line with the trajectory of "three-line construction"
There were seven large third-tier enterprises of Mingguang, Huaguang, Jinguang, Hongguang, Xingguang, Yongguang and Jianghua
The Great Wall and the Liaoyuan are lined with two small and third lines
It involves military industry, precision instruments, optical components, large machinery, bearings and cameras
In exceptional times
Filled with a special past
As the world situation changes
Factory relocation, restructuring, bankruptcy, suspension of production...
The "three-line construction" that was once in full swing disappeared into the foothills of Huaying Mountain
