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