Off the coast of Tanzania lies the breathtaking island of Zanzibar. For half a century, China has been sending teams of doctors there to treat people.
For the last 51 years, there has been one seasoned group of individuals on the island who have made a name for themselves.
Apart from working at a hospital there, the team members also visit rural areas to attend to free clinics and pass on skills that help people.
