Perhaps you should try some spelling variations:
chung cong » nhung cong, chong cong, phung cong
luan chung » luan chinh
chuc danh » chuc nganh, thuc hanh, chuc nang
hanh dung » thanh dung, anh dung, hanh dong
chu xanh » chieu xanh, chua xang, chu thanh
chu manh » ho manh, chu han, chu van
cong tac » cong ty
tac toan » tap toan, tam toan, hach toan
toan cau » toan cao, toan ban, toan tap

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 ((((chu xanh) OR (chuc danh))) OR (chu manh)) - hanh dung luan chung cong tac toan cau~.
• Adding a wildcard symbol may retrieve word variants: theo ((((chu xanh) or (chuc danh))) or (chu manh)) - hanh dung luan chung cong tac toan cau*.
