Perhaps you should try some spelling variations:
cua viet » ca viet, cua vat, cua dieu
tu sach » thu sach, su sach, te sach
va hanh » van hanh, va thanh, va danh
hanh di » hanh vi, hanh de, hang di
cua tre » cua te, cuu tre, cua triet
y nang » ky nang, ly nang, v nang
va cam » va cham, va cac, va cao
xuc va » duc va, tuc va, luc va
x hoi » xa hoi, o hoi, x ho

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 x hoi. lieu va cam xuc va hanh di ((cua tre) OR (((cua viet) OR (hoa viet))))~.
• Adding a wildcard symbol may retrieve word variants: tu sach y nang x hoi. lieu va cam xuc va hanh di ((cua tre) or (((cua viet) or (hoa viet))))*.
