Shaw Brothers productions during the late 1950s to early '60s were dominated by actresses like Li Li-Hua, Ivy Ling Po, Linda Lin Dai, Betty Loh Ti, Li Ching in dramatic and romantic features. In particular, the Huangmei opera "The Love Eterne", starring Ivy Ling Po and Betty Loh Ti and based on the "Butterfly Lovers" folk legend from the Jin Dynasty, is one of the highest-grossing features of the Shaw Studio. Its huge success is in part due to the ingenious casting of Ivy Ling Po, who was a relatively unknown supporting actress, as the male lead. In the story of "Butterfly Lovers", the female lead, played by Betty Loh Ti, disguised herself as a male to attend college because social mingling between the sexes was forbidden. The film resonated with its audience, and reportedly some members of the audience in Hong Kong and Taiwan repeatedly bought tickets and watched the feature in theaters over and over again in 1962, with some having watched it over 20 times.
