+  模拟UI场景。用途是容纳所有模拟UI组件，并与实际的UI进行信息交换。
+
+  在实际针对Scene与Handler进行开发时，Scene只需要创建Item并管理就行了，
+  与逻辑相关的代码都在RequestHandler及其子类中编写，然而直接负责管理各个
+  UI组件的是Scene。以下是注意事项：
+
+  1. 使用scene:update方法来更新Item的属性：
+  -------------------------------
+
+    [QML] cardItem.enabled = true;
+    [Lua] scene:update("CardItem", cid, { enabled = true })
+
+  这样做是为了在后续操作中能成功的将此处作出的修改传达给QML。因为没有类似QML的
+  属性绑定机制，因此要另外调用update方法来记录相关的属性变动。
+
+  2. 使用Scene提供的方法来访问元素
+  ---------------------------------
+
+  例如RoomScene中已经创建了表达卡牌和技能的Item，因此在Handler的逻辑编写中，
+  应当避免再去使用getCards或者getSkills这样获取原始属性的函数，而是直接访问Item
+  例如：
