Perhaps you should try some spelling variations:
ve triet » va trien, su triet
hanh ve » hanh vi, hanh va, hanh kem
te sach » toc sach
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
cam tuc » cam xuc, nam thuc, dam thuc
cam tu » cam thu, nam tu, dam tu
te sac » te cac, te san
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 sac) OR (te sach)) ky tang xa hoi. hieu ve ((cam tuc) or (cam tu)) va hanh ve ve triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sac) OR (te sach)) ky tang xa hoi. hieu ve ((cam tuc) OR (cam tu)) va hanh ve ve triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sac) OR (te sach)) ky tang xa hoi. hieu ve ((cam tuc) or (cam tu)) va hanh ve ve triet".
• Adding a wildcard symbol may retrieve word variants: ((te sac) OR (te sach)) ky tang xa hoi. hieu ve ((cam tuc) or (cam tu)) va hanh ve ve triet*.
