Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hanh dung » thanh dung, anh dung, hanh dong
cua nhung » va nhung
chu xanh » chieu xanh, chua xang, chuc danh
chu manh » ho manh, chu han, chu van
dung cua » dung luan, dung cho
dan toan » van toan, manh toan, xuan toan
dan than » dan chan, ban than, van than

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 cua nhung cong ((dan toan) OR (dan than)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) or (chu manh)) - hanh dung cua nhung cong ((dan toan) OR (dan than)) cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) or (chu manh)) - hanh dung cua nhung cong ((dan toan) OR (dan than)) cau*.
