Perhaps you should try some spelling variations:
viec lam » viec va
viec cac » vien cac, viec cua, viec va
hanh vai » hanh vi, hanh va, hanh tai
va hanh » van hanh, va thanh, va danh
nang xa » nang x, lang xa, nang ma
vu san » va san, vu ban
luc va » duc va, tuc va, loc va
san ky » sang 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 san ky nang xa hoi. hieu ((viec cac) or (viec lam)) luc va hanh vai ((cua te) OR (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu san ky nang xa hoi. hieu ((viec cac) OR (viec lam)) luc va hanh vai ((cua te) OR (cua tu))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu san ky nang xa hoi. hieu ((viec cac) or (viec lam)) luc va hanh vai ((cua te) OR (cua tu))*".
