Zou Yujiang (L) and Peng Zhengyong, a driver hired by Zou, are on the way back home from southeast China's Fujian Province to east China's Jiangxi Province, June 13, 2018. Zou makes a phone call to his family. 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.
