Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu xanh » chieu sach, chieu sang, chieu tinh
nhieu tang » chieu sang, hieu lang, nhiet nang
trung cua » truong cua, trung tuan, trung cap
cua thong » cua thuong, cua khong, cua tong
cong dan » cong tan, huong dan, cong dong
cong san » cong tac
than cau » toan cau, phan cau, than cap

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 (nhieu tang)) - thanh trung cua thong ((cong dan) OR (cong san)) than cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (nhieu tang)) - thanh trung cua thong ((cong dan) OR (cong san)) than cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (nhieu tang)) - thanh trung cua thong ((cong dan) OR (cong san)) than cau*.
