Perhaps you should try some spelling variations:
hanh trang » thanh trung, hanh trinh, minh trang
cua nhung » va nhung
chi sach » chinh sach, chieu sach, co sach
cua dang » cua cong, cua ban
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan cau » toan cao, toan ban, toan tap
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 sach - ((hanh trang) OR (canh tranh)) ((cua nhung) OR (cua dang)) cong dan toan cau~.
• Adding a wildcard symbol may retrieve word variants: doi chi sach - ((hanh trang) or (canh tranh)) ((cua nhung) or (cua dang)) cong dan toan cau*.
