Perhaps you should try some spelling variations:
chua xang » chua nang, chuc nang, chu bang
hanh tang » hanh trang, anh tang, hanh mang
dung cong » dung trong
chu xanh » chu manh, chieu xanh, chuc danh
tang cua » mang cua, hang cua, tang luan
cua dung » cua dang, cua dong, qua dung
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 (chua xang)) - hanh tang cua dung cong ((dan toan) OR (dan than)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) or (chua xang)) - hanh tang cua dung cong ((dan toan) OR (dan than)) cao~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) or (chua xang)) - hanh tang cua dung cong ((dan toan) OR (dan than)) cao*.
