Perhaps you should try some spelling variations:
thien van » thi van
su triet » su viet, su tien, ve triet
tham xuc » tham nuoc, tham thuc, pham duc
van tham » van thanh, van tuan, van chat
nang xa » nang x, lang xa, nang ma
sach va » sach xa, sach ha, sach dao
danh vi » hanh vi, danh di, danh va
dinh vi » dinh ve, dinh viet, dinh tri
sach v » sach y, sach 2, sach vay
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 v) OR (sach va)) nang xa hoi. thien van tham xuc va ((danh vi) OR (dinh vi)) su triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach v) or (sach va)) nang xa hoi. thien van tham xuc va ((danh vi) OR (dinh vi)) su triet~".
• Adding a wildcard symbol may retrieve word variants: te ((sach v) or (sach va)) nang xa hoi. thien van tham xuc va ((danh vi) OR (dinh vi)) su triet*.
