Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
chua xang » chua nang, chuc nang, chu bang
tinh bang » tinh sang, tinh lang, tinh quang
chu manh » ho manh, chu han, chu van
anh bang » anh hoang, anh quang, anh dong
cong san » cong tac
san toan » van toan, dan toan, manh toan
toan cau » toan cao, toan ban, toan tap

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 manh) OR (chua xang)) - ((anh bang) OR (tinh bang)) va nhung cong san toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu manh) or (chua xang)) - ((anh bang) OR (tinh bang)) va nhung cong san toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu manh) or (chua xang)) - ((anh bang) OR (tinh bang)) va nhung cong san toan cau*.
