The southern Chinese city of Dongguan in Guangdong province is one of the most important production lines in China, known as "the world's factory". With information technology as its pillar industry, Dongguan has witnessed a successful transformation from manufacturing to intelligent manufacturing over the past 30 years.

Thanks to new technologies, the city's traditional production reliance on low-cost labor and massive human resources has gradually been replaced by automation, digitization and intelligent production.

Traction Line, a new exhibition underway at the China Photography Exhibition Hall in Beijing, offers a glimpse of the new manufacturing life of the city, showcasing artwork by Dongguan-born photographer Li Zhiliang.
