Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
thanh dung » thanh duong, thanh tung, thanh hung
ho chieu » theo chieu, hoc thieu, doi chieu
vat dung » van dung, viet dung, mat duong
dan toan » van toan, dan than, manh toan
van than » van thanh, van thang, van tuan
va dung » van dung, va duong, 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 - thanh dung ((vat dung) OR (va dung)) cong ((dan toan) OR (van than)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - thanh dung ((vat dung) OR (va dung)) cong ((dan toan) or (van than)) cao~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - thanh dung ((vat dung) OR (va dung)) cong ((dan toan) or (van than)) cao*.
