Late on Saturday, cities near Zhengzhou, including Yuzhou, Changge and Qinyang, urged Foxconn workers to report to local authorities in advance before heading home.
Apple did not immediately reply to a Reuters request for comment on the Foxconn situation.
Photographs and videos circulating on Chinese social media since Saturday showed Foxconn workers, apparently returning home, trekking across fields in the day and along roads at night.
In a show of support, residents in the vicinity left bottled water and provisions next to roads with signs such as: “For Foxconn workers returning home,” according to social media posts.
“Some people were walking amid wheat fields with their luggage, blankets and quilts,” one user on WeChat, a popular social media platform, wrote about the images.
