江湖險惡
[jiāng hú xiăn è]
'The Perils of the Jianghu' (a term used in martial arts and historical context) implies living or operating in a dangerous and unpredictable environment. 'Jianghu' originally referred to rivers and lakes but evolved into a world outside the law or traditional society where adventurers, wandering heroes, or people with specific skills live by their own code.
