Perhaps you should try some spelling variations:
dam thuc » am thuc, dan thuc, nam thuc
ve triet » va trien, su triet
ky tang » ky nang, ky dang, kho tang
tang xa » trang xa, tang ma, lang xa
hieu ve » hieu va, hieu van
va hanh » van hanh, va thanh, va danh
hanh ve » hanh vi, hanh va, hanh kem
te van » le van, te va, ve van
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 van ky tang xa hoi. hieu ve ((dam thuc) or (cam xuc)) va hanh ve ve triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te van ky tang xa hoi. hieu ve ((dam thuc) OR (cam xuc)) va hanh ve ve triet.
• Adding a wildcard symbol may retrieve word variants: te van ky tang xa hoi. hieu ve ((dam thuc) or (cam xuc)) va hanh ve ve triet*.
