Perhaps you should try some spelling variations:
te sach » toc sach
sach ty » sach y, sach tu, sach thu
ty nang » ky nang, ty xang, ty hang
nang xa » nang x, lang xa, nang ma
qua cam » qua cham, qua cac, qua ca
cam tuc » cam xuc, cam tu, nam thuc
tuc van » thuc van, truc van, tuc va
hang di » hang doi, hang vi, hang dien
cua tre » cua te, cuu tre, cua triet

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 ty nang xa hoi. hieu qua cam tuc van ((hang di) OR (hanh vi)) cua tre~.
• Adding a wildcard symbol may retrieve word variants: te sach ty nang xa hoi. hieu qua cam tuc van ((hang di) or (hanh vi)) cua tre*.
