Perhaps you should try some spelling variations:
thuc va » thuc vat, thuc dan, thuc day
ky tang » ky nang, ky dang, kho tang
tang xa » trang xa, tang ma, lang xa
hieu ve » hieu va, hieu van
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
xuc va » duc va, tuc va, luc va
ve cam » ve cham, ve cac, va cam
ke ve » ke va, ke he, ke vi

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 ((xuc va) or (thuc va)) danh ((ke ve) OR (de ve)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky tang xa hoi. hieu ve cam ((xuc va) OR (thuc va)) danh ((ke ve) OR (de ve)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky tang xa hoi. hieu ve cam ((xuc va) or (thuc va)) danh ((ke ve) OR (de ve)) triet".
• Adding a wildcard symbol may retrieve word variants: te sac ky tang xa hoi. hieu ve cam ((xuc va) or (thuc va)) danh ((ke ve) OR (de ve)) triet*.
