Liu Ling has been a driver for Didi Express for two years. He admitted that he was a driver for an illegal unlicensed taxi. His home is in Beijing's suburban Shunyi District. Having a farm and a poultry farm, he didn't really work as an unlicensed taxi driver to make a living, but to get some pocket money. "Since Didi started the Express service, not many of my old peers still stick to that business," he said.
