Perhaps you should try some spelling variations:
cua tre » cua te, cuu tre, cua triet
thi van » thi lan, thi hanh, thi nang
danh vi » hanh vi, dinh vi, danh di
hieu ve » hieu va, hieu van
xay hoi » xa hoi, tay hoi, cay phoi
sac ky » cac ky, sai ky
lop va » hop va, nop va
lap va » tap va
va xay » va xac
vi cua » vai cua, di cua
tu sac » tu sach, tu cac, tu san
ky va » ly va, ke va, my va

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 va xay hoi. ((hieu ve) OR (thi van)) cac ((lop va) OR (lap va)) danh vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky va xay hoi. ((hieu ve) or (thi van)) cac ((lop va) OR (lap va)) danh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky va xay hoi. ((hieu ve) or (thi van)) cac ((lop va) OR (lap va)) danh vi cua tre*.
