gwai2 lou2 = a humorous way to call "foreigner(s)", it does not really mean literately "ghost men". Even those pretty Cantonese ladies who married "gwai2 lou2", they say "ngo5 lou2 gung1 hai6 gwai2 lou2 我老公系鬼佬 (my husband is a (white)foreigner. ) And their husbands willingly call themselves "ngo5 hai6 gwai2 lou2 我系鬼佬". That's why Ho Kwo Wing called himself "gwai2 ou2" here.
In our Cantonese dictionary, "gwai2 lou2" is a good word while "Chinaman" is a bad word.
Yes, Kwo Wing, we all love you, (gwai2 lou2)!
