If we can avoid intense joy, there will naturally be no sadness.

This sentence comes from one of the "third notes" of human disqualification in the first chapter. Repeat the same thing every day, following the same routine as yesterday. If we can avoid violent ecstasy, there will naturally be no sadness. Cheating each other, but surprisingly without any harm, even as if unaware of each other's deception, such undisguised and open-minded examples of mutual distrust abound in human life.

Disqualification in the World begins with my feelings after seeing three photos of Ye Zang. There are three annotations in the middle, and three annotations correspond to the photos. They respectively introduce Ye Zang's experiences in childhood, adolescence and prime of life, and describe how Ye Zang gradually lost his qualifications. In his works, Osamu Dazai cleverly hides his life and thoughts in the life experience of the protagonist Ye Zang, and through Ye Zang's monologue, he gets a glimpse of Osamu Dazai's inner world-"a life full of shame". In the same year that the work was published, Osamu Dazai committed suicide.
