Qi Hongrui, the most famous Peking Opera actor in Hankou. On the stage, he is the graceful Concubine Yang, and Liang Hongyu who beats drums and fights against Jinshan; off the stage, he is the "lone light" walking on the edge of a knife. In the darkest moments before the fall of Wuhan in 1938, he used his unparalleled elegance as a cover, and used his mysterious lyrics and body movements to convey information about the life and death of the battle to the meetings of senior Japanese military officials. Every chant is a gamble on life, and every flip of the sleeves is tied to the lives and deaths of millions of people. When the stage becomes a battlefield, he is the ghost who sings an unyielding elegy for the city under the gaze of the enemy.
