Xiong Dehua is about to become 30. It has been almost eight years since he came to find a job in Shanghai from his hometown in Chongqing. He worked as a builder and a parcel courier, both strenuous jobs. He entered Didi Express service half a year ago. Although the job still takes much effort, he eventually has started to feel settled, saying that it is the most stable and highest paying job he and his townspeople can find.
