there are four running errands on behalf of drivers. They are City Ruifeng Daidai Service Co., Ltd., Zhengshun Daidai Service Co., Ltd., Chenyu Daidai Service Co., Ltd. and Qianli Daidai Service Co., Ltd.. Driving on behalf of the driver means that when the owner can't drive to the destination by himself, a professional driver will drive the owner's car to the designated place and charge a certain fee. It is widely used in the catering industry. Car owners go to restaurants for dinner and drinking, and because they can't drive after drinking, others drive instead.
