Perhaps you should try some spelling variations:
chieu xanh » chieu sang, chieu tinh, hieu manh
chieu sach » chinh sach, chiet tach, chieu sang
trinh quan » tinh quang, trinh han
lang cong » dang cong, bang cong, hang cong
cong dan » cong san, cong tan, huong dan
dan can » dan chan, dan canh, dan ca
can ban » van ban, toan ban

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 sach)) - canh ((trinh quan) OR (trinh luat)) lang cong dan can ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu sach)) - canh ((trinh quan) OR (trinh luat)) lang cong dan can ban~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu sach)) - canh ((trinh quan) OR (trinh luat)) lang cong dan can ban*.
