早期作品-快递管理系统
'Early' means before my graduate period, when my major was not CS-related. These codes show little concept of 'software engineering', or say 'architecture', though some of them can be called 'project'.
“早期”指的是在我的研究生阶段之前（我本科所学专业与信息类完全无关）。这些代码很少有“软件工程”的概念，或者说很少有“架构设计”，尽管其中有几个的规模使得它们还是足以能被称为“工程项目”。
These codes are too troublesome to review, so i put them here merely for recording. To see my progress.
这些代码要review起来着实费劲，所以我把它们放在这里仅仅是为了记录。嗯，记录自己的成长历程哈哈哈。
This is a 'delivery management system', the 'big homework' of OOP course. Emmm, it's literally not a 'system', but something just for fun. 这是个所谓的“快递管理系统”，面向对象编程（C++）课的大作业。额，大概只能搞搞笑了吧2333
