Hu Die
In 1931, Hu Die starred in "Sing-Song Girl Red Peony" (dir. Zhang Shichuan), the first Chinese sound film (although it was sound-on-disc, not sound-on-film). Compared with other silent-era film stars, who were mostly southerners with poor Mandarin, Hu Die made the transition to sound with ease. She appeared in more sound films and was able to sing in "The Flower of Freedom", a real sound film of much higher quality.
