Perhaps you should try some spelling variations:
tu sach » thu sach, su sach, te sach
nang xa » nang x, lang xa, nang ma
va cham » va chat, va tham
soc van » hoc van, oc van, sac van
cuu tre » cau tren, cau treo
cua tre » cua te, cua triet, dua tren
y nang » ky nang, ly nang, v nang
anh vi » hanh vi, anh ve, anh vu
anh va » hanh va

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang xa hoi. lieu va cham soc van ((anh vi) OR (anh va)) ((cuu tre) OR (cua tre))~".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang xa hoi. lieu va cham soc van ((anh vi) OR (anh va)) ((cuu tre) OR (cua tre))*.
