Ba Jin had once drawn a self-portrait of himself:
Day and night the passion burned in me like a whip at my heart. Before my eyes were countless pictures of pain, of the sufferings of the majority and my own, which made my hands tremble. I kept writing. The environment was always so monotonous: in an empty room, in front of him was a square table piled with books, newspapers, and papers, next to the glass windows that let in sunlight, there was also an old sofa and two small round stools. My hand moved uncontrollably over the paper, as if many, many people were pouring out their sufferings through my hand. I forget myself, forget everything around me. I became a writing machine. I sometimes squatted on the chair, sometimes leaned my head on the square table, or stood up and walked to the sofa to sit down and write excitedly. And so I finished writing my novel Home and the other novellas
