Perhaps you should try some spelling variations:
van thanh » ban thanh, van tuan
tru nang » tra nang, tri nang, truc nano
vu sach » vu bach, vu khach
su sach » so sach
nang xa » nang x, lang xa, nang ma
qua cai » qua hai, qua cac, qua ca
cai xuc » cam xuc, chat xuc
cua tre » cua te, cuu tre, cua triet
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: ((vu sach) OR (su sach)) tru nang xa hoi. hieu qua cai xuc ((van ban) OR (van thanh)) vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) OR (su sach)) tru nang xa hoi. hieu qua cai xuc ((van ban) or (van thanh)) vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((vu sach) OR (su sach)) tru nang xa hoi. hieu qua cai xuc ((van ban) or (van thanh)) vi cua tre*.
