Perhaps you should try some spelling variations:
doc triet » hoc thiet, doc viet, soc thiet
ky tang » ky nang, ky dang, kho tang
tang xa » trang xa, tang ma, lang xa
hieu va » lieu va, hieu qua
thuc va » thuc vat, thuc dan, thuc day
danh va » doanh va, hanh va, anh va
va cam » va cham, va cac, va cao
xuc va » tuc va, luc va, xac va

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: tu cac ky tang xa hoi. hieu va cam ((((xuc va) or (duc va))) or (thuc va)) danh va doc triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky tang xa hoi. hieu va cam ((((xuc va) OR (duc va))) OR (thuc va)) danh va doc triet.
• Adding a wildcard symbol may retrieve word variants: tu cac ky tang xa hoi. hieu va cam ((((xuc va) or (duc va))) or (thuc va)) danh va doc triet*.
