Chinese media fabrication 
Huanqiu Sibuo printed article with a fake Seoul University Professor from a history department who is making claims that a Chinese historical figure/poet, was actually a Korean. First of all, there's no professor named Kim Byung Duk at SNU, and second of all, there is no history department at Seoul University.
