Perhaps you should try some spelling variations:
cua tre » cua te, cuu tre, cua triet
ky tang » ky dang, kho tang, ky trong
tinh va » tich va, trinh van, trinh vat
va tinh » may tinh
va cua » va chua, via cua, ca cua
luc va » duc va, tuc va, loc va
vu sac » vu sach, vu san, va sac
ve cac » va cac, vien cac
ve cau » ke cau, va cau, le cau

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: vu sac ((ky tang) OR (ky nang)) xa hoi. hieu ((ve cau) OR (ve cac)) luc va tinh va cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ((ky tang) or (ky nang)) xa hoi. hieu ((ve cau) OR (ve cac)) luc va tinh va cua tre~".
• Adding a wildcard symbol may retrieve word variants: vu sac ((ky tang) or (ky nang)) xa hoi. hieu ((ve cau) OR (ve cac)) luc va tinh va cua tre*.
