Song of Salted Fish Zhang San

My name is "Xianyu", not because I am really a salty fish! But because my name is Xian Yu! Why do I need to use the stage name Zhang San in the songs I write? In fact, I originally wanted to use dog-sun, iron pillars, etc... After all, the old man said, it's easy to make a living with a bad name! But after my sister argued hard with "reason" and convinced people with "reason"... I chose Zhang San, a name that everyone could barely accept.
