Perhaps you should try some spelling variations:
hanh dai » hanh tai, hanh dao, vanh dai
tu sach » thu sach, su sach, te sach
hieu va » lieu va, hieu qua
cam tuc » cam xuc, cam tu, nam thuc
va hanh » van hanh, va thanh, va danh
cua tre » cuu tre, cua triet, dua tren
y nang » ky nang, ly nang, v nang
va cam » va cham, va cac, va cao
tuc va » thuc va, truc va, tuc xa
cua te » cua tu

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: tu sach y nang ((xa hoi) OR (x ho)). hieu va cam tuc va hanh dai ((cua tre) OR (cua te))~.
• Adding a wildcard symbol may retrieve word variants: tu sach y nang ((xa hoi) or (x ho)). hieu va cam tuc va hanh dai ((cua tre) or (cua te))*.
