Why did Lu Xun give Fang a name like this?

The Collection of Justice is a collection of essays written by Lu Xun in 1927 and published in 1928. In the face of the slaughter of revolutionaries and progressives by reactionary warlords, Mr. Lu Xun was resentful and helpless. "In the past six months, I have seen a lot of blood and tears, but only mixed feelings. Tears wiped away, blood disappeared, and the Tubo people were happy again. And I only have' miscellaneous feelings'. When even' mixed feelings' are placed where they should go, I am just' just'. "

Inscription:

In the past six months, I have seen a lot of blood and tears.

However, I only have mixed feelings.

Tears wiped away and blood disappeared;

Tubo people are happy again,

Use a steel knife, use a soft knife.

However, I only have "miscellaneous feelings".

Even when "mixed feelings" are "put in the right place",

So I only have "just"!
