Perhaps you should try some spelling variations:
cac khoi » cac thoi, cac khoan, cach thoi
te sach » toc sach
hanh di » hanh vi, hanh de, hang di
va hanh » van hanh, va thanh, va danh
cam luc » cam xuc, cau luc
cua tre » cua te, cuu tre, cua triet
hieu va » hieu qua
y nang » ky nang, ly nang, v nang
luc va » duc va, tuc va, loc va
di cua » dai cua, doi cua, de cua

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 y nang ((xa hoi) OR (cac khoi)). ((hieu va) OR (lieu va)) cam luc va hanh di cua tre~.
• Adding a wildcard symbol may retrieve word variants: te sach y nang ((xa hoi) or (cac khoi)). ((hieu va) or (lieu va)) cam luc va hanh di cua tre*.
