What are the good old Cantonese songs?

Cantonese songs include Laughing at the Sea, Men Be Self-reliant, Drunken Boxing and so on. These songs are very classic and popular. Laugh and see that the sea comes from the legendary swordsman. Men should strive for self-improvement and sing heroes in the distance. The Cantonese version of Drunken Boxing was sung by Jackie Chan, which is also very nice!
