Commemorating the 70th anniversary of the victory of the Chinese People's War of Resistance against Japanese Aggression and the World Anti-Fascist War, the opera is set against the backdrop of the Chinese people's war against Japanese Aggression and depicts the transformation of Xian Xinghai's mind and heart during his work and life in Yan'an. The opera is a modern interpretation of the heroic spirit of the Yan'an base area, where the military and civilians fought to the death against the enemy in a time of national crisis.
