Perhaps you should try some spelling variations:
dung cong » dung trong
cong danh » cuong danh, cong dan, cong thanh
danh toan » manh toan, anh toan, dan toan
chu manh » chu han, chu van, thu minh
tang van » hoang van, trong van, tang luan
dang van » hoang van, hang va
toan cau » toan cao, toan ban, toan tap

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 manh) OR (ho manh)) - anh ((tang van) or (dang van)) dung cong danh toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chu manh) OR (ho manh)) - anh ((tang van) OR (dang van)) dung cong danh toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu manh) OR (ho manh)) - anh ((tang van) or (dang van)) dung cong danh toan cau".
• Adding a wildcard symbol may retrieve word variants: theo ((chu manh) OR (ho manh)) - anh ((tang van) or (dang van)) dung cong danh toan cau*.
