Perhaps you should try some spelling variations:
thanh loi » thanh hoa, thanh hai, thanh lap
van tham » van thanh, van tuan, van chat
hieu van » hieu va, thien van, lieu va
hanh lam » thanh lap, hanh kem, hanh va
tham xuc » tham nuoc, tham thuc, pham duc
sach ky » sac ky, sach y, sach kem
nang xa » nang x, lang xa, nang ma
sach ty » sach y, sach tu, sach thu
cua tre » cua te, cuu tre, cua triet
xuc va » duc va, tuc va, luc va

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 ky) OR (sach ty)) nang xa hoi. hieu van tham xuc va ((thanh loi) OR (hanh lam)) cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) OR (sach ty)) nang xa hoi. hieu van tham xuc va ((thanh loi) or (hanh lam)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) OR (sach ty)) nang xa hoi. hieu van tham xuc va ((thanh loi) or (hanh lam)) cua tre*.
