Chen has a video chat with his wife on his iPhone. Chen quit his job at the logistic company in 2014 to become a fulltime Private Car driver so as to make a higher wage to cover his wife's medical bills. "I had a fixed wage at the logistic company. Being a Private Car driver makes a higher income although it takes more effort." He now rents an executive car for his Didi service. It brings him quite a higher income than that in the past.
