老余并不老，３０多岁，只是我们学校教职工多为２０来岁的年轻人，相比之下，就叫他老余了。他中等个头，有点胖，走起路来两肩晃得很厉害。老余的脸上总是一团和气，一副笑呵呵的样子，说起话来慢悠悠的，很有韵味。据说，老余是支援山区教育的志愿者，原来在大城市洛阳教书 Old Yu is not old, more than 30 years old, but our school staff are mostly young people in their 20s. In contrast, he called him old. He is medium-sized and a little fat, walking up and down the shoulders and shaking. Old Yu’s face is always full of enthusiasm, a smiling face, talking slowly and very charm. It is said that Lao Yu is a volunteer who supports mountain education and originally taught in the big city of Luoyang.
