Perhaps you should try some spelling variations:
dinh vai » dinh van, dinh vi, dinh va
tu sach » thu sach, su sach, te sach
vai cua » dai cua, hai cua, lai cua
va dinh » van dinh, va kinh, va tinh
cua tre » cua te, cuu tre, cua triet
ty hang » ly hang, ty xang, thi hang
ty nang » ky nang, ty xang, ly nang
ve cac » va cac, vien cac
xuc va » duc va, tuc va, luc va
ve cam » ve cham, va cam, ve cai

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 ((ty nang) OR (ty hang)) xa hoi. hieu ((ve cam) OR (ve cac)) xuc va dinh vai cua tre~.
• Adding a wildcard symbol may retrieve word variants: tu sach ((ty nang) or (ty hang)) xa hoi. hieu ((ve cam) or (ve cac)) xuc va dinh vai cua tre*.
