Perhaps you should try some spelling variations:
thu sac » thu sach, thu san, thu xac
dinh vi » dinh ve, dinh viet, dinh tri
cuc ban » cua ban, cac ban, cuu ban
cua tre » cua te, cuu tre, cua triet
lang xa » lang ha, dang xay, lang van
ky lang » ky nang, ky dang, ky tang
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, ve cai
va cam » va cham, va cac, va cao

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: thu sac ky lang xa hoi. hieu ((ve cam) OR (va cam)) cuc ban ((dinh vi) OR (hanh vi)) cua tre~.
• Adding a wildcard symbol may retrieve word variants: thu sac ky lang xa hoi. hieu ((ve cam) or (va cam)) cuc ban ((dinh vi) or (hanh vi)) cua tre*.
