In 2001, Jiagang made a significant career shift, transitioning from architecture to become a full-time artist. This marked a turning point in his life, where he began to focus on capturing the changing landscape of China through photography. His photography career gained momentum in 2003 when he began working on his
Third Front series, later expanding to
The Great Third Front in 2008. These series focus on documenting the remnants of China's "Third Line" cities—vast military-industrial complexes built during the 1960s under
Mao Zedong’s directive to fortify China’s interior against potential threats. Jiagang’s large-format photographs present these cities as decaying remnants of a once-glorified industrial era, bringing attention to their fading collective memory and questioning their future relevance in a rapidly modernizing China. In 2002 and 2003, he received Excellent Works Prizes at the 20th and 21st China Photographic Exhibitions. multiple private collections. == Exhibitions ==
