Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
chieu xanh » chieu sach, chieu sang, chieu tinh
trinh quan » tinh quang, trinh luat, trinh han
hieu manh » hieu nganh, dieu hanh, hien hanh
quan dang » quang dang, quan lang, quan dong
dang cong » dung cong
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 ((hieu manh) OR (chieu xanh)) - hanh trinh quan dang cong dan van ban~.
• Adding a wildcard symbol may retrieve word variants: hoc ((hieu manh) or (chieu xanh)) - hanh trinh quan dang cong dan van ban*.
