Perhaps you should try some spelling variations:
te sach » toc sach
sach va » sach xa, sach ha, sach dao
va nang » van nang, da nang, cam nang
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
cua tre » cua te, cuu tre, cua triet
ve cam » ve cham, ve cac, va cam
xuc va » tuc va, xac va
luc va » tuc va, loc 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 va nang xa hoi. hieu ve cam ((((xuc va) OR (luc va))) OR (duc va)) hanh vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach va nang xa hoi. hieu ve cam ((((xuc va) OR (luc va))) or (duc va)) hanh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: te sach va nang xa hoi. hieu ve cam ((((xuc va) OR (luc va))) or (duc va)) hanh vi cua tre*.
