Perhaps you should try some spelling variations:
chau tinh » cuu tinh, ha tinh, cua tinh
hanh dung » thanh dung, anh dung, hanh dong
luan hung » luan chung, lan hung, luan ung
hung cong » nhung cong, hung cuong, phung cong
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 ((trieu tinh) OR (chau tinh)) - hanh dung luan hung cong dan ((toan cau) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((trieu tinh) or (chau tinh)) - hanh dung luan hung cong dan ((toan cau) OR (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: theo ((trieu tinh) or (chau tinh)) - hanh dung luan hung cong dan ((toan cau) OR (toan cao))*.
