Perhaps you should try some spelling variations:
cong thanh » dong thanh, cong trinh, cong tan
chau tinh » cuu tinh, cua tinh, cac tinh
hanh tang » hanh trang, anh tang, hanh mang
tang cua » mang cua, hang cua, tang luan
cua dang » cua cong, cua ban
cong san » cong tac
toan cao » toan ban, toan tap
ha tinh » va tinh, may tinh

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 ((chau tinh) OR (ha tinh)) - hanh tang cua dang ((cong thanh) OR (cong san)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chau tinh) OR (ha tinh)) - hanh tang cua dang ((cong thanh) or (cong san)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: theo ((chau tinh) OR (ha tinh)) - hanh tang cua dang ((cong thanh) or (cong san)) toan cao*.
