Perhaps you should try some spelling variations:
hanh tranh » canh tranh, hanh trinh, hanh trang
chuc danh » chuc nganh, thuc hanh, chuc nang
tranh cua » doanh cua, manh cua
bang cong » bang song, hang cong, dung cong
dang cong » dung cong
chu manh » ho manh, chu han, chu van
tan chan » dan chan, ban chan, can chan
chan cau » phan cau, can cau, chinh cau

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) OR (dang cong)) tan 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) OR (dang cong)) tan chan cau~".
• Adding a wildcard symbol may retrieve word variants: cho ((chuc danh) or (chu manh)) - hanh tranh cua ((bang cong) OR (dang cong)) tan chan cau*.
