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

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

• Performing a fuzzy search may retrieve terms with similar spellings: vu ban ky nang xa hoi. ((hieu viec) or (sieu viet)) cac ((luc va) OR (duc va)) hanh vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ban ky nang xa hoi. ((hieu viec) OR (sieu viet)) cac ((luc va) OR (duc va)) hanh vai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ban ky nang xa hoi. ((hieu viec) or (sieu viet)) cac ((luc va) OR (duc va)) hanh vai cua te*".
