Perhaps you should try some spelling variations:
chieu sach » chinh sach, chieu sang, chieu xanh
nhung cong » dung cong, thong cong, hang cong
hanh sinh » hanh tinh, hanh dinh, hinh sinh
cua nhung » va nhung
sinh cua » manh cua, dinh cuu, sinh va
cong dan » cong san, cong tan, huong dan
toan cau » toan ban, toan tap, toan tai
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 sach) OR (chiet tach)) - hanh sinh cua nhung cong dan ((toan cau) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) OR (chiet tach)) - hanh sinh cua nhung cong dan ((toan cau) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) OR (chiet tach)) - hanh sinh cua nhung cong dan ((toan cau) or (toan cao))*.
