Perhaps you should try some spelling variations:
hanh dung » thanh dung, anh dung, hanh dong
cong manh » cong danh, duong manh, cong thanh
chu xanh » chieu xanh, chua xang, chuc danh
chu manh » ho manh, chu van, thu minh
luan ung » luan hung, luon ung, luan chung
ung cong » dung cong, luong cong, duong cong
manh van » anh van, menh van, canh van
chu han » chu van

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 (((chu manh) OR (chu han)))) - hanh dung luan ung cong manh van ban~.
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) or (((chu manh) or (chu han)))) - hanh dung luan ung cong manh van ban*.
