Perhaps you should try some spelling variations:
cua tre » cua te, cuu tre, cua triet
hieu ve » hieu va, hieu van
lang xa » dang xay, lang van
do tuan » do xuan, do quang
cham do » cham o, pham do, tham do
lang ha » long ha
ve cham » va cham, ve chat, vu cham
vi cua » vai cua, di cua
anh vi » hanh vi, anh va, anh ve
sac ky » sai ky

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) OR (cac ky)) ((lang xa) OR (lang ha)) hoi. hieu ve cham do tuan anh vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sac ky) or (cac ky)) ((lang xa) OR (lang ha)) hoi. hieu ve cham do tuan anh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu ((sac ky) or (cac ky)) ((lang xa) OR (lang ha)) hoi. hieu ve cham do tuan anh vi cua tre*.
