笑忘江湖
[xiào wàng jiāng hú]
'Laugh Away All Worries in the World (of Jianghu)'. Jianghu in Chinese usually refers to the society among martial arts people in old times. In modern usage it may stand for any kind of complicated and chaotic society life outside. So this name suggests forgetting worldly worries and cares, and enjoying freedom as if nothing in the world can touch you.
