A few days ago, I heard a teacher tell me something that touched my heart: once, he accompanied a foreign teacher to visit the school library. The reading room of the library is crowded with people, and the students sit quietly reading. The two took a few steps inside, and the foreign teacher suddenly stopped. My teacher asked him strangely what happened and made a gesture of continuing to invite him in to have a look. You know, the library of this university is famous for its long history, magnificent architecture and elegant environment. Its history can be traced back to the self-improvement school library founded by Zhang Zhidong, governor of Huguang in the late Qing Dynasty, and it has been officially built for nearly 90 years. When scholars come to this university, almost all of them will visit this famous library. But the foreign teacher still stood still. He pointed to his feet, waved and looked around at the students who were immersed in their studies. Before my teacher understood, I saw that the foreign teacher suddenly bent down and quickly took off his shoes. Then he took them in his hand, with a relaxed look on his face and continued to walk barefoot. It turned out that he was worried that the sound of his leather shoes walking on the wooden floor would interfere with his classmates' study. I was moved by the details of foreign teachers walking barefoot in the library reading room. From this seemingly "awkward" but not so "dignified" move, I see not only a lovely humility in the face of historical relics, but also a heartfelt respect for others.
