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