提刀走江湖
[tí dāo zŏu jiāng hú]
The idiom 'wielding a knife and wandering in the rivers and lakes' originates from the Wulin Jianghu background, suggesting freedom and adventure while practicing martial arts, embodying wanderlust and the adventurous side of oneself. In ancient times in China, warriors or fighters wandered among different places. They carried knives and solved difficulties for the locals in need, helping those weaker than them.
