Perhaps you should try some spelling variations:
hieu viec » nhieu viec, sieu viet, hieu hien
hanh vai » hanh vi, hanh va, hanh tai
nang xa » nang x, lang xa, nang ma
vai cua » dai cua, hai cua, lai cua
hieu ve » hieu va, hieu van
vu san » va san, vu ban
luc va » duc va, tuc va, loc va
xuc va » duc va, tuc va, xac va
san ky » sang ky, van ky, dan ky
cua te » cua tu

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: vu san ky nang xa hoi. ((hieu viec) OR (hieu ve)) cam ((xuc va) OR (luc va)) hanh vai cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu san ky nang xa hoi. ((hieu viec) OR (hieu ve)) cam ((xuc va) or (luc va)) hanh vai cua te~".
• Adding a wildcard symbol may retrieve word variants: vu san ky nang xa hoi. ((hieu viec) OR (hieu ve)) cam ((xuc va) or (luc va)) hanh vai cua te*.
