我们的教学楼非常坚固,四面的墙壁都是70年代的大青石砌成的,厚度在一尺以上,加上里外全用水泥沙浆粉刷,更加坚固,用铜墙铁壁来形容一点也不为过。室外墙角处有通往楼上的自来水管和下水管,据说当时安装工人为了固定管道,动用了金钢钻孔机,在墙上打七八个钉眼足足花了一天工夫,累得直喊膀子疼,硬要会计多付10元工钱。 Our teaching building is very strong, all the walls are made of 70’s large bluestone, the thickness of more than one foot, plus inside and outside the whole with cement mortar stucco, more solid, with iron wall to describe the copper wall is not an exaggeration. Outside the corner of the corner leading to the upstairs water pipes and sewer pipes, it was said at the time the installer was said to have fixed the pipeline, using a steel drill, playing seven or eight studs on the wall took a full day, tired straight Shout arm ache, insist on accountant pay 10 yuan wages.
