Perhaps you should try some spelling variations:
hieu viec » nhieu viec, sieu viet, hieu hien
hanh vai » hanh vi, hanh va, hanh tai
va hanh » van hanh, va thanh, va danh
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
cac luc » cau luc, coc luc, cac nuoc
vu ban » tu ban, va ban
luc va » duc va, tuc va, loc va
ban ky » van ky, dan ky
cua tu » cua tuc, cua su, cua cu

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