Lu Xun can be said to be the most complex literary individual since ancient times. His complexity has gone beyond the boundaries of pure literature. He represents the transformation of the times, the cold analysis of the national soul, and the bold innovation of thinking methods. As Professor Yan Jiayan said, Lu Xun used the writing style of Pi Li Yang Qiu, which was unknowingly spoken out verbally, but actually had some praise, criticism and comments, which also inspired the reader's judgment.
The main idea of this passage is that Lu Xun's works are the most profound and complex.
