Perhaps you should try some spelling variations:
ve triet » va trien, su triet
danh ve » dinh ve, hanh ve, anh ve
thuc va » thuc vat, thuc dan, thuc day
tang xa » trang xa, tang ma, lang xa
hieu ve » hieu va, hieu van
xuc va » duc va, tuc va, luc va
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)) tang xa hoi. hieu ve cam ((xuc va) or (thuc 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 ((xuc va) OR (thuc 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 ((xuc va) or (thuc 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 ((xuc va) or (thuc va)) danh ve ve triet*.
