Niu Gur's first published cartoon appeared in Hong Kong's Overseas Chinese Daily. That was during the Mid-Autumn Festival (when the moon is full), and the cartoon showed a Chinese dropping a bomb-round in shape and glowing like the moon-on a soldier of the Japanese imperial army, with the caption "The War of Resistance by Moonlight."
牛哥第一張被發表的漫畫登載在香港的華僑日報；當天正是中秋節，他畫了一個中國人拿著圓形與月光對比的圓炸彈，點燃了引線向日本皇軍丟過去，題目是「月光下的抗戰」。
