A couple of years ago, Yuan Jianglei was a volunteer teacher at the Confucius Institute in the West African country of Benin. When his term was over there, he made a decision to come home to China by bike. The journey cost him almost a year, crossing 16 difference countries. But he didn't settle for that. He went back to Africa. This time to build wells and solar panel systems for the poverty-stricken local. CGTN's Tao Yuan sat down with him.
