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