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 » luc van, xuc ban, thuc van
duc van » duc va, duc tan, duc manh
hanh va » hang va, hanh vi
cua tre » cua te, cuu tre, cua triet
tu sac » tu sach, tu cac, tu san
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 sac ((ky lang) OR (ky dang)) xa hoi. hieu ve cam ((xuc van) OR (duc van)) hanh va cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ((ky lang) OR (ky dang)) xa hoi. hieu ve cam ((xuc van) or (duc van)) hanh va cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu sac ((ky lang) OR (ky dang)) xa hoi. hieu ve cam ((xuc van) or (duc van)) hanh va cua tre*.
