Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
hanh doanh » hang doanh, chinh doanh, doanh doanh
doanh cua » doanh luan
ban cong » bang cong, van cong, phan cong
san toan » dan toan, manh toan, xuan toan
van toan » van tuan, van tan, van thanh

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 sang)) - hanh doanh cua ban cong ((san toan) OR (van toan)) ban~.
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu sang)) - hanh doanh cua ban cong ((san toan) or (van toan)) ban*.
