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 phong » thuan phong, tran phong, luan phong
phong cong » phong chong, thong cong, chong cong
van thanh » ban thanh, van tuan
van than » van thang, van tuan, van phan

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