Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
theo chua » theo chu, ho chua, cheo cua
chua xang » chua nang, chuc nang, chu bang
tang luan » dung luan
mang cua » manh cua, dung cua, ban cua
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: theo chua xang - hanh ((tang luan) OR (mang cua)) nhung cong dan ((toan cau) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chua xang - hanh ((tang luan) or (mang cua)) nhung cong dan ((toan cau) OR (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: theo chua xang - hanh ((tang luan) or (mang cua)) nhung cong dan ((toan cau) OR (toan cao))*.
