Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
canh manh » canh tranh, cach mang, van manh
lanh manh » lanh tranh, lan anh, van manh
dang cong » dung cong
ho chieu » theo chieu, hoc thieu, doi chieu
cong dan » cong san, cong tan, huong dan
toan tai » toan tap, doanh tai, toan cao
toan ban » van ban
va dang » van dang, va nang, va lang

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 - ((canh manh) OR (lanh manh)) va dang cong dan ((toan tai) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((canh manh) OR (lanh manh)) va dang cong dan ((toan tai) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((canh manh) OR (lanh manh)) va dang cong dan ((toan tai) or (toan ban))*.
