Former military correspondent Yang Hongxiang shares his experience documenting how combat engineer corps helped build the infrastructure of the Shenzhen Special Economic Zone (SEZ) in the early 1980s during a photo exhibition held at the library of Shenzhen University in Shenzhen, south China's Guangdong Province, Sept. 22, 2020. Yang had worked as a military correspondent with the first combat engineers who pioneered the construction of the Shenzhen SEZ. With photos and stories, he documented the rapid change of Shenzhen -- high-rise buildings mushrooming from barren lands, tarmacked avenues replacing dirt roads, public facilities such as museum, theater and airport rising from scratch. "Forty years ago I was recording this city and now I'm building it," says Yang, who owns an urban development business. "As a resident of Shenzhen, I've witnessed how it burgeoned and I truly take pride in the achievements we made." (Xinhua/Mao Siqian)
