Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
nang xa » nang x, lang xa, nang ma
van cac » van hac, van cau, van bac
cac tac » cac toc, cac bac, cac dac
va hanh » van hanh, va thanh, ban hanh
va danh » va dinh, va dan, dia danh
cua tre » cua te, cuu tre, cua triet
su sac » su sach, su xac
su cac » tu cac, su cao, su can

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: ((su sac) OR (su cac)) ky nang xa hoi. hieu van cac tac ((va hanh) OR (va danh)) dai cua tre~.
• Adding a wildcard symbol may retrieve word variants: ((su sac) or (su cac)) ky nang xa hoi. hieu van cac tac ((va hanh) or (va danh)) dai cua tre*.
