Ayooo.... I read all the reply, so kan-chiong already, no one
got tell boi boi the very important solution and secret that
char-bo has and can use.
If front door cannot go in, use the back door lah. That is the
reason why nature give char-bo 2 doors. Use the emergency door to
go in first and when the cha-bo siok leow, she will unlock the
front door the next time you visit...
