Perhaps you should try some spelling variations:
va hanh » van hanh, va thanh, ban hanh
dai huu » dao huu, dai hau, dai thua
va danh » va dinh, va dan, dia danh
huu tre » huu tri, cuu tre, huu them
vu cham » va cham, vu kham, tu cham
va cam » va cham, va cac, va cao
te cac » tu cac, ve cac, te cao
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: te cac ky nang x hoi. hieu ((va cam) OR (vu cham)) tuc ((va hanh) OR (va danh)) dai huu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te cac ky nang x hoi. hieu ((va cam) or (vu cham)) tuc ((va hanh) OR (va danh)) dai huu tre~".
• Adding a wildcard symbol may retrieve word variants: te cac ky nang x hoi. hieu ((va cam) or (vu cham)) tuc ((va hanh) OR (va danh)) dai huu tre*.
