Perhaps you should try some spelling variations:
xuong cong » luong cong, duong cong, cuong cong
canh thanh » canh tranh, danh thanh, anh thanh
xung cong » luong cong, duong cong, cuong cong
dung cong » dung trong
theo chu » theo chieu, cho chu, chao chu
chu xanh » chu manh, chieu xanh, chua xang
tran van » luan van

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

• Performing a fuzzy search may retrieve terms with similar spellings: theo chu xanh - canh thanh thuy ((((xung cong) OR (dung cong))) or (xuong cong)) tan tran van~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu xanh - canh thanh thuy ((((xung cong) OR (dung cong))) OR (xuong cong)) tan tran van.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - canh thanh thuy ((((xung cong) OR (dung cong))) or (xuong cong)) tan tran van".
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - canh thanh thuy ((((xung cong) OR (dung cong))) or (xuong cong)) tan tran van*.
