Perhaps you should try some spelling variations:
hanh hoi » hanh thoi, hanh noi, hanh hoa
lang van » dang van, tang van, hoang van
van hanh » van thanh, ban hanh, van anh
hieu van » hieu va, thien van, lieu va
te sach » toc sach
cam tuc » cam xuc, cam tu, nam thuc
lang xa » lang ha, dang xay
hoi cua » hoi chuc
hieu ve » hieu va
tuc van » thuc van, truc van, tuc va
cua su » qua su

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 sach y ((lang xa) OR (lang van)) hoi. ((hieu ve) OR (hieu van)) cam tuc van hanh hoi cua su~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((lang xa) or (lang van)) hoi. ((hieu ve) OR (hieu van)) cam tuc van hanh hoi cua su~".
• Adding a wildcard symbol may retrieve word variants: te sach y ((lang xa) or (lang van)) hoi. ((hieu ve) OR (hieu van)) cam tuc van hanh hoi cua su*.
