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
trung tuan » trung thanh, trung tam, tran tuan
tuan hoang » quan hoang, tran hoang, xuan hoang
danh toan » anh toan, dan toan, dang toan
manh toan » thanh toan, anh tuan, tinh toan

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: hoc ((chieu xanh) OR (chieu sach)) - thanh trung tuan hoang vuong ((danh toan) OR (manh toan)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) or (chieu sach)) - thanh trung tuan hoang vuong ((danh toan) OR (manh toan)) cao~".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu xanh) or (chieu sach)) - thanh trung tuan hoang vuong ((danh toan) OR (manh toan)) cao*.
