Perhaps you should try some spelling variations:
chieu xanh » chieu sang, chieu tinh, hieu manh
chieu sach » chinh sach, chiet tach, chieu sang
hanh tran » hanh trang, thanh tran, hanh tram
dung cong » dung trong
duc dung » duc hung, duc cuong, duc trung
cong san » cong tac
toan ban » van ban

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chieu xanh) OR (chieu sach)) - hanh tran duc dung cong san ((toan tap) or (toan ban))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sach)) - hanh tran duc dung cong san ((toan tap) OR (toan ban))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sach)) - hanh tran duc dung cong san ((toan tap) or (toan ban))*".
