敢掀刘海见人敢掌掴贱人
[găn xiān liú hăi jiàn rén găn zhăng guāi jiàn rén]
'Dare to flip the fringe and confront people, dare to slap scumbags in front of everyone.' This shows courage and audacity in dealing directly with offensive or obnoxious individuals, implying an independent spirit and not hesitating to confront wrongdoings publicly.
