+# `Opus`, `Article`, `Dynamic`
+
+~~不得不说阿 b 真会整活~~
+
+为防止许多人对这三个类之间的关系、定义不理解，下文将作出详细解释。
+
+## 1. 定义
+
+- `Opus`: 图文。可用于访问链接为 `https://www.bilibili.com/opus/***`。
+- `Article`: 专栏。可用于访问链接为 `https://www.bilibili.com/read/cv***`。
+- `Dynamic`: 动态。可用于访问链接为 `https://t.bilibili.com/***`。
+
+例如崩坏星穹铁道的版本更新说明，可以用以下两个链接访问：
+
+- `https://www.bilibili.com/read/cv27705422/`
+- `https://www.bilibili.com/opus/863994527716737095`
+
+所以这个版本更新说明既是专栏，又是图文。
+
+## 2. 分类
+
+接下来我们对各个类之间的关系进行一个梳理：
+
+```
+                                                        |---------|
+  专栏图文       +     公开笔记     +     普通专栏     =    | Article |
+                                                        |---------|  
+
+     +    
+
+  动态图文 
+
+     =    
+           
+|---------|                              |---------|
+|   Opus  |     +    普通动态      =      | Dynamic |
+|---------|                              |---------|
+```
+
+## 3. 解析
+
+1. 部分专栏和动态发布时，会自动转成图文，但是他们还是属于动专栏和动态。
+2. 在创建图文之后，也会对专栏创建对应动态。大概率是因为图文的 `API` 部分是直接照抄动态的来用的。因此所有的图文全部属于动态。
+3. 剩下不是图文的专栏或者动态，即为普通专栏和普通动态。
+4. 公开笔记会以专栏的形式存在。
+
+## 4. 模块提供的类之间的转换
