RM30k should be enough for everything bcs the angpows will help you pay for the dinner. Today's young people don't understand the role of the angpow in a wedding. It's to help one family celebrate the marriage of their child. So it's a community effort. People are actually paying for their dinner and relatives/friends who are rich will give more than the actual price of the dinner to help out with other expenses like liquor etc.

I think if you're a man your parents must at least ask her parents,maybe through somebody. Do not take things for granted or your parents could lose face. Tolong give them face and make them proud.

Yes,you had better to be on the safe side. Buy after the wife is safely in your bed hahaha
