Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
van hanh » van thanh, ban hanh, van anh
hieu ve » hieu va
va hanh » va thanh, va danh, ban hanh
vai cua » dai cua, hai cua, lai cua
tu van » tu va
cua cu » cua chu, cua cau, cua su
x hoi » xa hoi, o hoi, x ho

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

• If you are trying to use Boolean operators, they must be ALL CAPS: tu van ky nang x hoi. ((hieu ve) OR (hieu van)) phan tu ((va hanh) OR (van hanh)) vai cua cu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu van ky nang x hoi. ((hieu ve) OR (hieu van)) phan tu ((va hanh) or (van hanh)) vai cua cu~".
• Adding a wildcard symbol may retrieve word variants: tu van ky nang x hoi. ((hieu ve) OR (hieu van)) phan tu ((va hanh) or (van hanh)) vai cua cu*.
