There is no entry of "avant-garde poetry" in Ci Hai and Modern Chinese Dictionary. The word "avant-garde poetry" has been frequently used with the reform and opening up since the mid-1980s. No one had ever given a scientific definition of "avant-garde poetry" before Jiang Hai's article "Carved Dragon China's Pioneer Poetry". Jiang Hai Diao Long thinks: "Pioneer poetry refers to the latest and revolutionary poetry."
