Perhaps you should try some spelling variations:
hanh dung » thanh dung, anh dung, hanh dong
luan hung » luan chung, lan hung, tuan hung
chu xanh » chieu xanh, chua xang, chuc danh
chu manh » ho manh, chu han, chu van
luan ung » luon ung, luan chung, luan luong
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.

• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chu xanh) OR (chu manh)) - hanh dung ((luan hung) OR (luan ung)) cong dan than cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) or (chu manh)) - hanh dung ((luan hung) OR (luan ung)) cong dan than cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) or (chu manh)) - hanh dung ((luan hung) OR (luan ung)) cong dan than cau*.
