This could be the synopsis to be picked up as people entered the hall. The story is based on the 1940 novel with the same name. The film was made and released in July 1943, and here at Capital Theatre, its showing started on September 8, 1956, three times a day - 2:30 pm, 6:30 pm and 9:15 pm. Its Chinese film title was well selected, I may say.
Given the famous story line and well-known actor and actress, the audience turn out must have been very high.
