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
vai cua » dai cua, hai cua, lai cua
va san » va ban
san ky » sang ky, van ky, dan ky
loc va » hoc va, luc va
cua te » cua tu
x hoi » xa hoi, o hoi, 5 hoi

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