Perhaps you should try some spelling variations:
ve triet » va trien, su triet
ky tang » ky nang, ky dang, kho tang
tang xa » trang xa, tang ma, lang xa
danh ve » dinh ve, hanh ve, anh ve
thuc va » thuc vat, thuc dan, thuc day
te sac » te sach, te cac, te san
xuc va » duc va, tuc va, luc va
sac ky » cac ky, sai ky
ve cam » ve cham, va cam, ve cai
ve cac » va cac, vien cac
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) OR (ve cac)) ((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 tang xa hoi. hieu ((ve cam) OR (ve cac)) ((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 tang xa hoi. hieu ((ve cam) OR (ve cac)) ((xuc va) or (thuc va)) danh ve ve triet".
• Adding a wildcard symbol may retrieve word variants: te sac ky tang xa hoi. hieu ((ve cam) OR (ve cac)) ((xuc va) or (thuc va)) danh ve ve triet*.
