Perhaps you should try some spelling variations:
lanh tranh » canh tranh, lan tranh, hanh trinh
chieu xanh » chieu sach, chieu sang, chieu tinh
lanh manh » lan anh, van manh, anh anh
cua nhung » va nhung
ho chieu » theo chieu, hoc thieu, doi chieu
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
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: ho chieu xanh - ((lanh manh) OR (lanh tranh)) cua nhung ((cong dan) OR (cong tan)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((lanh manh) OR (lanh tranh)) cua nhung ((cong dan) or (cong tan)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((lanh manh) OR (lanh tranh)) cua nhung ((cong dan) or (cong tan)) toan cao*.
