Perhaps you should try some spelling variations:
qua cham » qua hai, qua cac, va cham
te sach » toc sach
nang xa » nang x, lang xa, nang ma
xuc van » duc van, luc van, thuc van
xuc ban » duc ban, cuc ban, quoc ban
cuu tre » cau tren, cau treo
cua tre » cua te, cua triet, dua tren
y nang » ky nang, ly nang, v nang

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: te sach y nang xa hoi. hieu qua cham ((xuc van) or (xuc ban)) hanh vi ((cuu tre) OR (cua tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang xa hoi. hieu qua cham ((xuc van) OR (xuc ban)) hanh vi ((cuu tre) OR (cua tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang xa hoi. hieu qua cham ((xuc van) or (xuc ban)) hanh vi ((cuu tre) OR (cua tre))*".
