Perhaps you should try some spelling variations:
thien van » thi van
hanh dieu » han dieu, hinh dieu, hoang dieu
dieu cua » dieu tra
van hanh » van thanh, ban hanh, van anh
chuc van » chu van, chuc va, thuc van
cau chuc » cau chu, cau phuc, canh chuc
cua tre » cua te, cuu tre, cua triet
hieu ve » hieu va, hieu van
lang xa » lang ha, dang xay, lang van
nang xa » nang x, nang ma, mang xa
sac ky » cac ky, sai ky
te sac » te sach, te cac, te san

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: te sac ky ((nang xa) OR (lang xa)) hoi. ((hieu ve) OR (thien van)) cau chuc van hanh dieu cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky ((nang xa) OR (lang xa)) hoi. ((hieu ve) or (thien van)) cau chuc van hanh dieu cua tre~".
• Adding a wildcard symbol may retrieve word variants: te sac ky ((nang xa) OR (lang xa)) hoi. ((hieu ve) or (thien van)) cau chuc van hanh dieu cua tre*.
