Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hanh tang » hanh trang, anh tang, hanh mang
van nhung » van nhuong, va nhung, van hung
chu xanh » chu manh, chieu xanh, chua xang
chu bang » thu bang, chuc nang, chu quang
tang van » dang van, hoang van, trong van
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 bang)) - hanh tang van 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 bang)) - hanh tang van nhung cong ((dan toan) OR (dan than)) cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) or (chu bang)) - hanh tang van nhung cong ((dan toan) OR (dan than)) cau*.
