Spurt blood to pollute oneself

The origin of Idioms
Zhang Juzheng's answer to Hu Yuwu on the Cao River in the Ming Dynasty said, "if you steal a false name, you don't know that you are first caught in the crime of a large group. The so-called" spitting blood to pollute yourself "means that you can't seek a name. It's hateful and you can also mourn."
