Perhaps you should try some spelling variations:
te sach » toc sach
hieu va » lieu va, hieu qua
danh vi » hanh vi, dinh vi, danh di
sach va » sach xa, sach ha, sach dao
hieu vu » hieu ve, hieu su, dieu vu
lang xa » lang ha, dang xay, lang van
va lang » va nang, hoa lang
cua tre » cua te, cuu tre, cua triet
xuc va » duc va, luc va, xac va
tuc va » thuc va, truc va, tuc xa
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 va lang xa hoi. ((hieu vu) OR (hieu va)) cham ((xuc va) OR (tuc va)) danh vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach va lang xa hoi. ((hieu vu) OR (hieu va)) cham ((xuc va) or (tuc va)) danh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: te sach va lang xa hoi. ((hieu vu) OR (hieu va)) cham ((xuc va) or (tuc va)) danh vi cua tre*.
