Perhaps you should try some spelling variations:
viec cac » vien cac, viec cua, viec lam
hanh vai » hanh vi, hanh va, hanh tai
va hanh » van hanh, va thanh, va danh
va san » va ban
san ky » sang ky, van ky, dan ky
loc va » hoc va, luc va
cua tu » cua tuc, cua su, cua cu
x hoi » xa hoi, o hoi, x ho

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

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