Perhaps you should try some spelling variations:
ky lang » ky nang, ky tang, tay lang
ky dang » ky nang, ky danh
hieu ve » hieu va, hieu van
xuc van » duc van, luc van, xuc ban
hanh va » hang va, hanh vi
cua tre » cua te, cuu tre, cua triet
ve cam » ve cham, ve cac, va cam
va cua » va chua, via cua, ca 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: tu cac ((ky lang) OR (ky dang)) xa hoi. hieu ve cam ((xuc van) OR (duc tan)) hanh va cua tre~.
• Adding a wildcard symbol may retrieve word variants: tu cac ((ky lang) or (ky dang)) xa hoi. hieu ve cam ((xuc van) or (duc tan)) hanh va cua tre*.
