Ask an old Hong Kong martial arts movie

When he was very young, he only remembered that there was a person who worked for an assassin group. The owner of the guild was a left-handed sword, and there was also a sword in the sleeve. In the end, when he fought with the killer boss, he killed him with the sword in his sleeve.
This movie was at least from the 1980s. I remember that when the protagonist went to kill someone, the other party had a sword hidden in a stick. I didn't expect the protagonist's left hand to be faster than his right hand. In the end, when he had a duel with the boss, the boss had already clamped his neck with his hand, but he had the sword in his sleeve to kill the other party.
I remember that the boss seems to like to sing opera. She often sang on stage in movies.
