一入江湖愁满腹
[yī rù jiāng hú chóu măn fù]
Literally, it means 'Once Entered the World(Imply Jianghu,a special term for the circle or society in traditional culture), Worries Flood In'. In China, 'jianghu' is not only the society itself but also stands for the world full of various people and relationships, filled with joy, anger, love and hatred. Therefore, the nickname reflects that life is hard to go through without any difficulties.
