Hong Kong Movie: Dressed as a Maintenance Worker and Thrown into the Sea to Feed the Fish

He was reborn and lived as a pauper in Xiangjiang for two years, relying on his connections to work as a maintenance worker in Ping An Building. I saw a serial murderer committing murder in the middle of the night and beat him to death with his heavy hand. Now I'm sitting in the female inspector's office being interrogated, and there's still someone waiting outside to kill me. In these miserable days, I might as well go back to Lamma Island to guard the pond.
