Li Guangping, a 65-year-old woman from Beijing, recently discovered a version of the popular ride-hailing app DiDi Express specially designed for seniors. This version features larger Chinese characters, a simplified user interface, and an option to “order a DiDi taxi with one click.” “My family helped me enter the destination address that I use frequently, and now all I have to do is to press a button to call a DiDi car. It's very convenient,” she said.
