Perhaps you should try some spelling variations:
hanh tranh » canh tranh, hanh trinh, hanh trang
tranh cua » doanh cua, manh cua
dang cong » dung cong
chi xanh » chi anh, chi danh, chi hanh
cua dang » cua cong, cua ban
cong dan » cong san, cong tan, huong dan
toan cau » toan cao, toan ban, toan tai
toan tap » toan ban
doi chi » doi khi

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: doi chi xanh - hanh tranh cua dang cong dan ((((toan cau) OR (van ban))) OR (toan tap))~.
• Adding a wildcard symbol may retrieve word variants: doi chi xanh - hanh tranh cua dang cong dan ((((toan cau) or (van ban))) or (toan tap))*.
