Perhaps you should try some spelling variations:
chieu sang » chieu sach, chieu xanh, hieu lang
hanh dung » thanh dung, anh dung, hanh dong
cong danh » cuong danh, cong dan, cong thanh
danh toan » manh toan, anh toan, dan toan
luan ung » luan hung, luon ung, luan chung
ung cong » dung cong, luong cong, duong cong
toan cao » toan ban, toan tap

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: theo ((chieu sang) OR (chinh sach)) - hanh dung luan ung cong danh toan cao~.
• Adding a wildcard symbol may retrieve word variants: theo ((chieu sang) or (chinh sach)) - hanh dung luan ung cong danh toan cao*.
