Perhaps you should try some spelling variations:
cong thanh » dong thanh, cong trinh, cong tan
theo phap » thi phap
phap tinh » phap sinh, phap tieng, phap tang
hanh tang » hanh trang, anh tang, hanh mang
tang cua » mang cua, hang cua, tang luan
cua dang » cua cong, cua ban
cong san » cong tac
toan cao » toan tap
toan ban » van 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: theo phap tinh - hanh tang cua dang ((cong thanh) OR (cong san)) ((toan cao) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo phap tinh - hanh tang cua dang ((cong thanh) or (cong san)) ((toan cao) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: theo phap tinh - hanh tang cua dang ((cong thanh) or (cong san)) ((toan cao) OR (toan ban))*.
