Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu xanh » chieu sang, chieu tinh, hieu manh
chieu sach » chinh sach, chiet tach, chieu sang
cong thanh » dong thanh, cong trinh, cong tan
trung cua » truong cua, trung tuan, trung cap
dong bang » dong san
cua dang » cua cong, cua ban
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: ho ((chieu xanh) OR (chieu sach)) - thanh trung cua dang ((dong bang) OR (cong thanh)) phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sach)) - thanh trung cua dang ((dong bang) or (cong thanh)) phan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sach)) - thanh trung cua dang ((dong bang) or (cong thanh)) phan cau*.
