Perhaps you should try some spelling variations:
chuc danh » chuc nganh, thuc hanh, chuc nang
hanh dung » thanh dung, anh dung, hanh dong
luan hung » luan chung, lan hung, luan ung
cong manh » duong manh, cong thanh, hoang manh
cong danh » cuong danh, cong dan, cong thanh
chu manh » ho manh, chu han, chu van
toan ban » van ban

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 ((chuc danh) OR (chu manh)) - hanh dung luan hung ((cong manh) OR (cong danh)) toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chuc danh) or (chu manh)) - hanh dung luan hung ((cong manh) OR (cong danh)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: theo ((chuc danh) or (chu manh)) - hanh dung luan hung ((cong manh) OR (cong danh)) toan ban*.
