"Farewell to Chao Ci" takes the war during the Republic of China as the background and focuses on the underground struggle. Communist Yan Anyu used his status as a returnee to publish anti-imperialist and anti-Kuomintang texts; Ji Cichu was actually a comrade of our party lurking within the Kuomintang, secretly delivering information and performing special tasks. In the turbulent intelligence battlefield, the two of them collaborated tacitly to deliver key information due to the intertwining of their faith and mission, or had misunderstandings and conflicts due to the fog of identity. In a dangerous environment, between loyalty and disguise, they wrote a spy war chapter about faith, perseverance and secret confrontation, showing the passion and sacrifice of revolutionary workers in a special era.
