Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu xanh » chieu sach, chieu sang, hieu manh
chieu tinh » trieu tinh, lieu tinh, chau tinh
van dung » van dong, xay dung, tin dung
cong san » cong tac
san than » sang than, san thanh, ban than
than cau » toan cau, phan cau, than cap
va dung » va duong, vat dung, va ung

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