Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
chuc danh » chuc nganh, thuc hanh, chuc nang
chua xang » chua nang, chuc nang, chu bang
hang mang » hang hang, hang mong, hanh mang
cua nhung » va nhung
mang cua » manh cua, dung cua, ban cua
dan than » dan chan, ban than, van than
van tan » van tuan, van ban, van tai

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 (chua xang)) - hang mang cua nhung cong ((dan than) OR (van tan)) cau~.
• Adding a wildcard symbol may retrieve word variants: theo ((chuc danh) or (chua xang)) - hang mang cua nhung cong ((dan than) or (van tan)) cau*.
