Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
truc va » thuc va, thuc vat, trung va
danh vi » hanh vi, dinh vi, danh di
te sach » toc sach
v nang » va nang, vu nang, van nang
sach v » sach va, sach y, sach 2
tuc va » thuc va, tuc xa, duc va
vi cua » vai cua, di cua

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 nang xa hoi. ((hieu ve) OR (lieu va)) cham ((tuc va) OR (truc va)) danh vi cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach v nang xa hoi. ((hieu ve) or (lieu va)) cham ((tuc va) OR (truc va)) danh vi cua triet~".
• Adding a wildcard symbol may retrieve word variants: te sach v nang xa hoi. ((hieu ve) or (lieu va)) cham ((tuc va) OR (truc va)) danh vi cua triet*.
