Gulangyu Island, which is just a short ferry ride from the city of Xiamen in southeast China, is well known to holidaymakers. A UNESCO World Cultural Heritage Site, it's one of China's most visited tourist attractions. But for many elderly residents of the island, it's the visit of an 80-year-old man they most look forward to. Fu Qingjiang has been giving free haircuts to seniors on Gulangyu for six decades. For the many who have difficulty walking, this little favor matters.
