Perhaps you should try some spelling variations:
chieu xanh » chieu sang, chieu tinh, hieu manh
chieu sach » chinh sach, chiet tach, chieu sang
doanh phan » doanh nhan, doan phan, doanh thanh
canh manh » lanh manh, canh tranh, cach mang
dung cong » dung trong
manh cua » doanh cua, ban cua
cua dung » cua dang, cua dong, qua dung
dan chan » dan gian, dan ca, van chat

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: hoc ((chieu xanh) OR (chieu sach)) - canh manh cua dung cong ((dan chan) OR (doanh phan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) OR (chieu sach)) - canh manh cua dung cong ((dan chan) or (doanh phan)) cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu xanh) OR (chieu sach)) - canh manh cua dung cong ((dan chan) or (doanh phan)) cau*.
