Perhaps you should try some spelling variations:
dam thuc » am thuc, dan thuc, nam thuc
van hanh » van thanh, ban hanh, van anh
ve triet » va trien, su triet
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
hanh ve » hanh vi, hanh va, hanh kem
te cac » tu cac, ve cac, te cao
ve ve » de ve, va ve, ke ve

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

• Performing a fuzzy search may retrieve terms with similar spellings: te cac ky nang xa hoi. hieu ve ((dam thuc) or (cam xuc)) van hanh ve ve triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te cac ky nang xa hoi. hieu ve ((dam thuc) OR (cam xuc)) van hanh ve ve triet.
• Adding a wildcard symbol may retrieve word variants: te cac ky nang xa hoi. hieu ve ((dam thuc) or (cam xuc)) van hanh ve ve triet*.
