Perhaps you should try some spelling variations:
chieu xanh » chieu sang, chieu tinh, hieu manh
chieu sach » chinh sach, chiet tach, chieu sang
thanh dung » thanh duong, thanh tung, thanh hung
dan toan » van toan, dan than, manh toan
toan cao » toan ban, toan tap
va dong » van dong, ha dong, lao dong
xa dong » ha dong, van dong, lao dong

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chieu xanh) OR (chieu sach)) - thanh dung ((va dong) or (xa dong)) huong dan toan cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sach)) - thanh dung ((va dong) OR (xa dong)) huong dan toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sach)) - thanh dung ((va dong) or (xa dong)) huong dan toan cao".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sach)) - thanh dung ((va dong) or (xa dong)) huong dan toan cao*.
