Perhaps you should try some spelling variations:
ky tang » ky nang, kho tang, ky trong
ky dang » ky nang, ky danh
lai hoi » dai hoi, lai hoa, lai roi
hieu ve » hieu va, hieu van
ve chat » va chat, van chat
tu sac » tu sach, tu cac, tu san
xuc va » tuc va, luc va, xac va
vi cua » vai cua, di cua
cua te » cua tu

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 tang) OR (ky dang)) lai hoi. hieu ve chat ((xuc va) OR (duc va)) hanh vi cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ((ky tang) OR (ky dang)) lai hoi. hieu ve chat ((xuc va) or (duc va)) hanh vi cua te~".
• Adding a wildcard symbol may retrieve word variants: tu sac ((ky tang) OR (ky dang)) lai hoi. hieu ve chat ((xuc va) or (duc va)) hanh vi cua te*.
