Perhaps you should try some spelling variations:
thuc tuan » thu tuan, thuc huan, thuc luan
cac thuc » cach thuc, cac thu, can thuc
te sach » toc sach
nang xa » lang xa, nang ma, mang xa
hieu va » lieu va
cua tre » cua te, cuu tre, cua triet
anh vi » hanh vi, anh va, anh ve
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 y ((nang xa) OR (nang x)) hoi. ((hieu va) OR (hieu qua)) cac thuc tuan anh vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((nang xa) OR (nang x)) hoi. ((hieu va) or (hieu qua)) cac thuc tuan anh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: te sach y ((nang xa) OR (nang x)) hoi. ((hieu va) or (hieu qua)) cac thuc tuan anh vi cua tre*.
