Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
danh vai » danh sai, danh va, doanh van
hieu van » hieu va, thien van, lieu va
cua tre » cua te, cuu tre, dua tren
va danh » va dinh, va dan, va hanh
te sach » toc sach
cac xuc » cam xuc, cac nuoc, chat xuc
hieu ve » hieu va
sang xa » song xa, lang xa, sang ma
xuc va » duc va, tuc va, luc va

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

• If you are trying to use Boolean operators, they must be ALL CAPS: te sach _ sang xa hoi. ((hieu ve) OR (hieu van)) cac xuc va danh vai ((cua tre) OR (cua triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach _ sang xa hoi. ((hieu ve) or (hieu van)) cac xuc va danh vai ((cua tre) OR (cua triet))~".
• Adding a wildcard symbol may retrieve word variants: te sach _ sang xa hoi. ((hieu ve) or (hieu van)) cac xuc va danh vai ((cua tre) OR (cua triet))*.
