Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
doi chieu » doc hieu, doi chi, ho chieu
canh manh » canh tranh, cach mang, van manh
lanh manh » lanh tranh, lan anh, van manh
dung cong » dung trong
ban thanh » ban hanh, ban hang
cua dung » cua dang, cua dong, qua dung
ban than » van thanh, ban hang, ban hanh

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: doi chieu xanh - ((canh manh) OR (lanh manh)) cua dung cong ((ban than) OR (ban thanh)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu xanh - ((canh manh) OR (lanh manh)) cua dung cong ((ban than) or (ban thanh)) cau~".
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - ((canh manh) OR (lanh manh)) cua dung cong ((ban than) or (ban thanh)) cau*.
