Perhaps you should try some spelling variations:
luan chung » luan chinh
luan hung » lan hung, luan ung, tuan hung
chua nang » chuc nang, chua xang, kha nang
anh dung » anh dong, anh huong, sach dung
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cau » toan cau, phan cau, than cap

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: cho ((ho manh) or (chua nang)) - anh dung ((luan hung) OR (luan chung)) cong dan than cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: cho ((ho manh) OR (chua nang)) - anh dung ((luan hung) OR (luan chung)) cong dan than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cho ((ho manh) or (chua nang)) - anh dung ((luan hung) OR (luan chung)) cong dan than cau".
• Adding a wildcard symbol may retrieve word variants: cho ((ho manh) or (chua nang)) - anh dung ((luan hung) OR (luan chung)) cong dan than cau*.
