Zhang said that he liked military books since he was a child, and now there are more than 300 books in the bookcase. "I will buy more books to enrich myself, so I am the poorest in our class." Zhang joked.
In the eyes of science teacher Huang, Zhang is smart, active in thinking and reads a lot. "I like to ask questions in class, and sometimes I haven't missed a class. Once in class, he talked about' buoyancy'. He raised his hand and kept asking questions. He also popularized the relationship between buoyancy and displacement for the students at the scene, and listed the displacement of ships and aircraft carriers. A small brain contains a lot of knowledge. "
