Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
chua xang » chuc nang, chu bang, chua dong
chua nang » chuc nang, kha nang, cuu nang
cua nhung » va nhung
hanh han » hanh nhan, hanh phan, hanh san
cong dan » cong san, cong tan, huong dan
gian cau » gian chau, gian cac, gian cu
gian cam » gian cham, gian cac, gia cam
han cua » hang cua, nhan cua, than cua

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) OR (chua nang)) - hanh han cua nhung cong dan ((gian cau) OR (gian cam))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chua xang) OR (chua nang)) - hanh han cua nhung cong dan ((gian cau) or (gian cam))~".
• Adding a wildcard symbol may retrieve word variants: theo ((chua xang) OR (chua nang)) - hanh han cua nhung cong dan ((gian cau) or (gian cam))*.
