Perhaps you should try some spelling variations:
hanh trang » thanh trung, canh tranh, hanh trinh
chieu xanh » chieu sach, chieu sang, chieu tinh
hieu manh » hieu nganh, dieu hanh, hien hanh
chua nang » chuc nang, chua xang, kha nang
chu bang » thu bang, chuc nang, chu quang
cong dan » cong san, cong tan, huong dan
dan van » dang van, doan van, dao van

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: hoc ((chieu xanh) OR (hieu manh)) - hanh trang ((chu bang) OR (chua nang)) cong dan van ban~.
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu xanh) or (hieu manh)) - hanh trang ((chu bang) or (chua nang)) cong dan van ban*.
