Perhaps you should try some spelling variations:
tu sach » thu sach, su sach, te sach
cua tre » cua te, cua triet, dua tren
sach va » sach xa, sach ha, sach dao
cuu tre » cau tren, cau treo
va cham » va chat, va tham
hieu va » lieu va, hieu qua
nang xa » nang x, lang xa, nang ma
va nang » van nang, da nang, cam nang
xuc xa » tuc xa
buc xa » tuc xa

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

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