本周推荐：《如此打工30年》

作者：占有兵

推荐：小编1号

带给我非常多小惊喜的一个作者。从1995年开始，到南方打工，各种生活的细节，都记录下来。那个时候我记得还是没有数码相机或者智能手机（那是20年之后的事情了），但是作者很有动力和毅力的保留了非常多当时的原始小票、证件、收据、手写便笺等，并留下了令我惊叹的日常生活的照片。那应该还是胶卷的时代，胶片贵，打工的钱很少，坚持下来非常不容易。文字的部分简短朴素，没有AI味道的朴素让我非常的沉迷，而简单文字中描述的每个人的小故事又时不时让我惊心动魄。

图书的简介中提到作者拍摄了超过150万张照片，打工相关的实物资料超过6吨。也得过很多照片的奖。还举办过照片的作品展出。

我很开心能够遇到这本书，让我能够仿佛沉浸在作者的环境中体验我没有体验过的30年。
