Perhaps you should try some spelling variations:
nhung cong » thong cong, hang cong, nhung don
chuc danh » chuc nganh, thuc hanh, chuc nang
hanh manh » hanh mang, lanh manh, hoang manh
dung cong » dung trong
chu manh » ho manh, chu han, chu van
manh cua » doanh cua, ban cua
ban cau » bang cau, ban can, van 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: theo ((chuc danh) OR (chu manh)) - hanh manh cua ((nhung cong) OR (dung cong)) van ban cau~.
• Adding a wildcard symbol may retrieve word variants: theo ((chuc danh) or (chu manh)) - hanh manh cua ((nhung cong) or (dung cong)) van ban cau*.
