Perhaps you should try some spelling variations:
chiet tach » chieu sach
hanh trang » thanh trung, canh tranh, hanh trinh
nhung cong » thong cong, hang cong, nhung don
trang cua » tranh cua, tang cua, trung cua
dung cong » dung trong
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 cua ((nhung cong) OR (dung 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 cua ((nhung cong) OR (dung cong)) dan phan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chinh sach) or (chiet tach)) - hanh trang cua ((nhung cong) OR (dung cong)) dan phan cau*.
