Perhaps you should try some spelling variations:
te sach » toc sach
cua tre » cua te, cua triet, dua tren
thuc va » thuc vat, thuc dan, thuc day
cuu tre » cau tren, cau treo
ve chat » va chat, van chat
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
xuc va » duc va, tuc va, luc va
sach v » sach va, sach y, sach 2
v nang » va nang, vu nang, van nang

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 chat ((xuc va) OR (thuc va)) hanh vi ((cua tre) OR (cuu tre))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach v nang xa hoi. hieu ve chat ((xuc va) or (thuc va)) hanh vi ((cua tre) OR (cuu tre))~".
• Adding a wildcard symbol may retrieve word variants: te sach v nang xa hoi. hieu ve chat ((xuc va) or (thuc va)) hanh vi ((cua tre) OR (cuu tre))*.
