In Cantonese, the lead character's surname, "Mo", is a homonym of a word that approximately means "no/will not/without/will never" (depending on the context of the sentence). In that sense, Mo Jup-shu's name means "Will never lose any opportunity". The son's name, Mo Dut Go, means "will never grow tall".
The name "Kum Dai Tse" is a pun, intended to satire South Korean politician (and later President) Kim Dae Jung.
