what Shaw series is this?

Hi guys, I have been curious abt title of a series that I watched in the early 1990s. I was still 9 yr old so I did not know the actor's name but somehow when I saw David Chiang's pic, his face is very familiar and I was sure he starred in this series. I searched through his movies and the story of Blood Brothers is similar to the series I was looking for. Plus, there is also a character named Ma Hsin Yi that I can recall. However, from what I remember, David Chiang's character in the series that I watched is a villain that betrayed his brother and it kinda opposed to the character he played in Blood Brothers so I am still unsure if I got the correct title. I have the opening and ending song from old cassette tape that I ripped. I wonder if anyone is familiar with the theme song and could let me know what is the title of the series?
