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