Perhaps you should try some spelling variations:
chiet tach » chieu sach
hanh trang » thanh trung, hanh trinh, minh trang
nhung cong » dung cong, thong cong, hang cong
cua nhung » va nhung
cong dan » cong san, cong tan, huong dan
dan phan » doan phan, dan chan, van phan
phan cau » phan dau, phan cac, phan tu

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 ((chinh sach) OR (chiet tach)) - ((hanh trang) OR (canh tranh)) cua nhung cong dan phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chinh sach) or (chiet tach)) - ((hanh trang) OR (canh tranh)) cua nhung cong dan phan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chinh sach) or (chiet tach)) - ((hanh trang) OR (canh tranh)) cua nhung cong dan phan cau*.
