进行一次思想和政治路线方面的教育

The poster features a young worker wearing a brown jacket over a red shirt and a cap, with a white towel draped around his neck. He raises one hand toward the sheet music while holding a rolled publication marked "红旗" (Red Flag) in the other. The sheet music and lyrics for "國際歌" (The Internationale), the famous communist anthem, are displayed beside him. The background shows factories and marching workers under red flags. The large red slogan in Chinese at the bottom states: "进行一次思想和政治路线方面的教育" (Carry out education on ideology and the political line).
