Perhaps you should try some spelling variations:
phung cong » nhung cong, phong cong, nhung chong
hanh dung » thanh dung, anh dung, hanh dong
hung cong » nhung cong, hung cuong, dung cong
chu xanh » chu manh, chieu xanh, chua xang
dan than » dan chan, ban than, van than
than cau » toan cau, phan cau, than cap
chu han » chu van

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