Zou Yujiang prepares for unloading goods at a construction materials market in Changting County, southeast China's Fujian Province, June 13, 2018. Zou Yujiang, 41 years old, is a truck driver from Gao'an City of Jiangxi Province. He has spent most of his time on the road, transporting goods from one place to another. There have been over 21 million employees in the industry of the road freight transportation in China so far. Like Zou Yujiang, most of them make a living on trucks with little time staying with families. Their hard works have contributed to the fast and reliable delivery services of the country.
