So this is fairly standard Shaw Brother's fare.
This isn't the best of the best, but I think it deserves 5 stars over 4.
Chang Cheh directs - which is generally enough for me to enjoy a kung fu film.
Standard learn specialized training to beat the kung fu skills of the main bad guys.
5 sets of training sequences. 2 boss level villians, 2 evil lieutenants, and a bunch of Manchu minions (not to be confused with Manchu soliders that usually carry spears or are requiped with a bow and arrows).
Chi Kuan-chun and Alexander Fu Sheng (which always make a great pair or, at least, they are often paired together like Ti Lung and David Chiang) along with Gordon Liu and a bunch of other martial artist from the Shaw Brothers stable.
Suprise appearence of Yuen Siu-tien aka Sam the Seed!
... and the non-standard (for Chang Cheh films) appearance of two love interests, but don't think that makes this a date-movie. Basically, it's the Black Dynamite thing; "How many times have I told you not to call me and interrupt my kung fu?"
