Perhaps you should try some spelling variations:
cua tre » cua te, cuu tre, cua triet
ky dang » ky nang, ky danh
dang xa » dang xay, lang xa, dang ha
dinh ve » dinh ket, dinh van
cuc ban » cua ban, cac ban, cuu ban
tu sac » tu sach, tu cac, tu san
ve cac » va cac, vien cac
sac ky » cac ky, sai ky
ve tai » te tai, de tai, le tai

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 sac ky dang xa hoi. hieu ((ve tai) OR (ve cac)) cuc ban ((hanh vi) OR (dinh ve)) cua tre~.
• Adding a wildcard symbol may retrieve word variants: tu sac ky dang xa hoi. hieu ((ve tai) or (ve cac)) cuc ban ((hanh vi) or (dinh ve)) cua tre*.
