Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
anh truong » manh truong, anh thuong, anh trong
truong cao » truong dai
cao trong » cao truong, cay trong, tao trong
ho chieu » theo chieu, hoc thieu, doi chieu
cong dan » cong san, cong tan, huong dan
toan cao » toan ban
toan tap » 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 sach - anh truong cao trong cong dan ((toan cao) OR (toan tap))~.
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - anh truong cao trong cong dan ((toan cao) or (toan tap))*.
