A 31-year-old man named Li Chengjian transformed a piece of brick into a flute-like instrument and he uses it to play music. Li can also play music on his unique DIY flutes, which he made out of a plastic pipe and a bicycle pump. Li says he came up with the idea of making his own instrument since he could not afford a proper one. The autodidact learned how to make flutes online after over a hundred unsuccessful attempts.
