The 1961 original version in black and white is a classic until today so far as Chinese movies is concerned. It stars the one and only Lin Dai. However, the second version (1970) in full color is also a classic, starring the popular Jenny Hu, whom I consider is one of the superstars of the Shaw Brothers era. Both are classics, with original musical score which is also timeless classic. I love more the 1970 version.
