I personally didn't watch that show, but from the screen captures I saw this guy calling her mom. What's up with that? mom? he looked only at most 10 years younger than her. did she have him when she was 10 or what?

he he, if i never saw Lady Fan i would have the same reaction too.

*small little spoiler*
Sit Ying Lung(Power Chan) makes a bet with Lei Fa. If she loses she will have to be his wife, if she wins he will be his son. Yeah Lei Fa wins both times . And Ying Lung keep his promise by calling her mother. She he is like an adopted son.
