Perhaps you should try some spelling variations:

chuc danh » chuc nganh, thuc hanh, chuc nang
tranh cua » doanh cua, manh cua
bang cong » dang cong, bang song, hang cong
chu manh » ho manh, chu han, chu van
cua bang » chua bang, cua ban, cua dang
tan chan » dan chan, can chan, tam chan
ban chan » dan chan, ban than, ban nhan

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: cho ((chuc danh) OR (chu manh)) - hanh tranh cua bang cong ((tan chan) OR (ban chan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cho ((chuc danh) or (chu manh)) - hanh tranh cua bang cong ((tan chan) OR (ban chan)) cau~".
• Adding a wildcard symbol may retrieve word variants: cho ((chuc danh) or (chu manh)) - hanh tranh cua bang cong ((tan chan) OR (ban chan)) cau*.
