This year I put this ang pow of RM168 under my pillow. It sounds like 'yat loh fat' which is meant for prosperity. It's a belief so it should work when you believe it.
Last year I just put in RM16.80. This year I put in more hoping to be more prosperous..
and furthermore it's for Good Luck too..
Wishing all of you a prosperous new year and good luck.
