Perhaps you should try some spelling variations:
thuc dan » thuc hanh, hoc dan, thuc vat
te sach » toc sach
sach vu » sach va, sach tu, sach uu
vu dang » su dang, vu quang, cua dang
dang xa » dang xay, lang xa, dang ha
hieu ve » hieu va, hieu van
ve chat » va chat, van chat
cua tre » cua te, cuu tre, cua triet
xuc va » duc va, tuc va, luc 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 vu dang xa hoi. hieu ve chat ((xuc va) OR (thuc dan)) hanh vi cua tre~.
• Adding a wildcard symbol may retrieve word variants: te sach vu dang xa hoi. hieu ve chat ((xuc va) or (thuc dan)) hanh vi cua tre*.
