The Foxconn plant in Zhengzhou, Henan province, was disinfected and cleaned thoroughly on Saturday during an outbreak of COVID-19, to offer a safe and secure environment for workers.

More than 2,000 people participated in the treatment and comprehensive disinfection work in the 5.6 million-square-meter compound, organized by the local authorities. It is the world's largest Apple iPhone assembly plant.

"The coronavirus mainly spreads via the air, so frequent disinfection is necessary," said Sun Jianli, deputy general manager of Cleaner Environment, one of the companies involved in the cleaning work. "We use both machines and human labor to disinfect employees' apartments three times a day. We have to work overtime to offer a good living environment for workers."
