Perhaps you should try some spelling variations:
va thanh » gia thanh, ban thanh, va tinh
so sang » so sanh, so dang, so lang
sang ky » sang kyo, dang ky, tang ky
qua cac » cua cac
cac xuc » cam xuc, cac nuoc, chat xuc
xuc va » duc va, tuc va, luc va
vi cua » vai cua
di cua » dai cua, doi cua, de cua
x hoi » xa hoi, o hoi, 5 hoi

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: so sang ky nang ((x hoi) OR (x ho)). hieu qua cac xuc va thanh ((vi cua) OR (di cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sang ky nang ((x hoi) OR (x ho)). hieu qua cac xuc va thanh ((vi cua) or (di cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: so sang ky nang ((x hoi) OR (x ho)). hieu qua cac xuc va thanh ((vi cua) or (di cua)) tre*.
