The other day, my teacher told me something: once, he accompanied a foreign teacher to visit the school library. The reading room of the library was packed, and the students were reading quietly. The two men took a few steps inside, and the foreign teacher suddenly stopped. He asked strangely what was wrong and made a gesture of continuing to invite him in. Foreign teachers are still marking time. He pointed to his feet, waved and looked around at the students who were immersed in their studies. Before he understood, the foreign teacher suddenly squatted down, quickly took off his shoes and held them in his hand. There was a relaxed expression on his face and he continued to walk barefoot. It turned out that he was worried that the sound of leather shoes stepping on the wooden floor would disturb students' study!

I was deeply moved by the details of foreign teachers marching barefoot in the library reading room. From this somewhat embarrassing and seemingly majestic move, what I see is a heartfelt respect for others.
