Perhaps you should try some spelling variations:
ky tang » kho tang, ky trong, tay tang
ky dang » ky danh
hieu ve » hieu va, hieu van
cau luc » cau truc, cau phuc
va tinh » may tinh
tinh vi » trinh vi, tinh voi, tinh va
cua tre » cua te, cuu tre, cua triet
vu sac » vu sach, vu san, va sac
ve cau » ke cau, va cau, ve cac
luc va » duc va, tuc va, loc va
vi cua » vai cua, di cua

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 dang))) OR (ky nang)) xa hoi. hieu ve cau luc va tinh vi cua tre~.
• Adding a wildcard symbol may retrieve word variants: vu sac ((((ky tang) or (ky dang))) or (ky nang)) xa hoi. hieu ve cau luc va tinh vi cua tre*.
