Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hanh trinh » hanh chinh
theo hieu » theo chieu, theo tieu, thien hieu
hieu lang » chieu sang, hieu quang, nhieu tang
cua nhung » va nhung
cong dan » cong san, cong tan, huong dan
toan cau » toan ban, toan tap, toan tai
toan cao » toan ban, toan tap

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: theo hieu lang - ((canh tranh) OR (hanh trinh)) cua nhung cong dan ((toan cau) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo hieu lang - ((canh tranh) or (hanh trinh)) cua nhung cong dan ((toan cau) OR (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: theo hieu lang - ((canh tranh) or (hanh trinh)) cua nhung cong dan ((toan cau) OR (toan cao))*.
