Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
manh toan » thanh toan, anh tuan, tinh toan
ho chieu » theo chieu, hoc thieu, doi chieu
chinh ta » chinh tai, chinh va, chinh tri
dan toan » dan than, xuan toan, dien toan
van toan » van tuan, van tan, van thanh
ta dung » tac dung, tan dung, tao dung

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 - hanh chinh ta dung trong ((((dan toan) OR (manh toan))) OR (van toan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh chinh ta dung trong ((((dan toan) OR (manh toan))) or (van toan)) cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh chinh ta dung trong ((((dan toan) OR (manh toan))) or (van toan)) cau*.
