History & Context
Mianyang's identity is rooted in the Third Front movement of the 1960s, when China relocated critical defense research facilities deep inland. The China Academy of Engineering Physics (CAEP), which leads nuclear weapons research, was established in nearby mountains and later moved to Mianyang. This concentration of defense R&D institutes led to Mianyang's unique designation as a "Science and Technology City" in 2001. Changhong Electric, originally a defense electronics plant, converted to civilian TV manufacturing and became a major consumer brand. The city continues to bridge defense technology and civilian applications.
