Perhaps you should try some spelling variations:
de triet » ve triet, de thiet, su triet
ky tang » ky nang, ky dang, kho tang
tang xa » trang xa, tang ma, lang xa
hieu ve » hieu va, hieu van
danh va » doanh va, hanh va, anh va
thuc va » thuc vat, thuc dan, thuc day
te sac » te sach, te cac, te san
tuc va » truc va, tuc xa, duc va
sac ky » cac ky, sai ky
xuc va » duc va, luc va, xac va
ve cam » ve cham, ve cac, va cam
va de » va do, va le

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 (tuc va))) or (thuc va)) danh va de 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 (tuc va))) OR (thuc va)) danh va de 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 (tuc va))) or (thuc va)) danh va de triet".
• Adding a wildcard symbol may retrieve word variants: te sac ky tang xa hoi. hieu ve cam ((((xuc va) OR (tuc va))) or (thuc va)) danh va de triet*.
