Perhaps you should try some spelling variations:
nhieu viec » hieu viec, nhien viet
hanh vai » hanh vi, hanh va, hanh tai
nang xa » nang x, lang xa, nang ma
cuc van » chuc van, cuu van, duc van
cac van » cac dan
vu dan » vu dang, va dan, cu dan
dan ky » van 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 dan ky nang xa hoi. nhieu viec cua ((cuc van) OR (cac van)) hanh vai ((cua te) or (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu dan ky nang xa hoi. nhieu viec cua ((cuc van) OR (cac van)) hanh vai ((cua te) OR (cua tu))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu dan ky nang xa hoi. nhieu viec cua ((cuc van) OR (cac van)) hanh vai ((cua te) or (cua tu))*".
