Perhaps you should try some spelling variations:
trung thanh » truong thanh
chieu xanh » chieu sach, chieu sang, chieu tinh
trung tuan » trung tam, tran tuan, truong thanh
dang cong » dung cong
cong dan » cong san, cong tan, huong dan
dan chan » dan gian, dan ca, van chat
chan cau » phan cau, can cau, chinh cau

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 ((chieu xanh) OR (trieu tinh)) - manh ((trung tuan) OR (trung thanh)) dang cong dan chan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) or (trieu tinh)) - manh ((trung tuan) OR (trung thanh)) dang cong dan chan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (trieu tinh)) - manh ((trung tuan) OR (trung thanh)) dang cong dan chan cau*.
