The Merry Month of May (1955)

Rich heiress Man Yu-sau disguises as a flower peddler in search of a genuine lover; her poor cousin Man Bik poses as a rich heiress to ensnare a husband. The two fall in love with the Wu brothers Lap-ming and Lap-tak respectively. The Wu matriarch despises Yu-sau for her humble background. However, Lap-ming elopes to marry her while Lap-tak marries Bik. The disguises are duly exposed, to the mother's embarrassment.
