In December 1937, the Japanese army invaded Nanjing, China’s ancient capital. Within a few weeks, more than 300,000 civilians and soldiers were brutally massacred. The puppet “Nanjing Municipal Self-Government Committee,” the puppet “Reformed Government of the Republic of China,” and the puppet “Wang Jingwei Government of the Republic of China” soon took the stage in succession. Told from the perspective of Liu Chang’an, an uneducated nobody, the story follows his perilous and humiliating journey through that era. Trained by Japanese spies and forced to assume various identities as both a Japanese and Chinese spy, he struggles to survive and grow.
