The 1940 film China Nights (支那の夜), also known as Shanghai Nights (上海の夜), by Manchuria Film Productions, is especially controversial. It is unclear whether it was a "National Policy Film" as it portrays Japanese Soldiers in both positive and negative Lights. In this film, Li Xianglan played a young woman of extreme anti-Japanese sentiment who falls in love with a Japanese man. A key turning point in the film has the young Chinese woman being slapped by the Japanese man, but instead of hatred, she reacts with gratitude. The film was met with great aversion among the Chinese audience as they believed that the Chinese female character was a Sketch of debasement and inferiority. 23,000 Chinese people paid to see the film in 1943. But after the war, one of her classic songs, "Suzhou Serenade" (蘇州夜曲), was banned in China and continues to be. A few years later when confronted by angry Chinese reporters in Shanghai, Yoshiko apologized and cited as pretext her inexperienced youth at the time of filmmaking, choosing not to reveal her Japanese identity. Though her Japanese nationality was never divulged in the Chinese media until after the Sino-Japanese War, it was brought to light by Japanese press when she performed in Japan under her assumed Chinese name and as the Japan-Manchuria Goodwill Ambassadress. Oddly enough, when she visited Japan during this period, she was criticized for being too Chinese in dress and in language.
