One thing about marrying normal viet gal is to be able to acccept their past. Due to their background and poor living conditions, many of them are either
(1) married to taiwanese at very young age, kanna abused and returned to Vietnam;
(2) worked as WL before or still working as one when you meet her;
Unlike Singaporean ladies who are brought up with good education and better living conditions, these viet gals do more things than 1 to feed their large family. So if you plan to marry one, do accept her past. Let her know that you do not dispise her and you love her for who she is. You are willing to create a future with her. Patience, love and care will change her. Do not lie to her, let her know the conditions in Singapore. For example, i watch the chinese news with my wife and i explain to her about the different news, from foreign ones to local ones. No need to lie, sooner or later they will know the truth.
