-### 支持的 Java 类型
-以下的 Java 类型可以直接转换到 JavaScript 中使用:
+### 支持的类型
+
+#### 以下基础类型，Java 和 JavaScript 可以直接互转使用
 - `boolean`
-- `int` 
+- `int`
 - `double`
 - `String`
-- `null` 
+- `null`
+
+#### JS 对象类型的互转
 - `JSObject` 代表一个 JavaScript 对象
 - `JSFunction` 代表一个 JavaScript 方法
 - `JSArray` 代表一个 JavaScript 数组
-
+
+#### 关于 Long 类型
+因为 JavaScript 里没有对应 Java 的 Long 类型，所以，Long 类型的转换比较特殊。
+- 从 Java 可以直接传 Long 值到 JavaScript，会转为 Int64 位。
+- 从 JavaScript 传值到 Java 转为为 Long 类型，需要借助 Double 类型，示例如下：
+    ```Java
+    ((Double)target).longValue());
+    ```
+

-### Supported Java Types
-Currently, the following Java types are supported with JavaScript:
+### Supported Types
+
+#### Java and JavaScript can directly convert to each other for the following basic types
 - `boolean`
 - `int` when calling JavaScript from Java.
 - `double`
 - `String`
 - `null`
+
+#### Mutual conversion of JS object types
 - `JSObject` represents a JavaScript object
 - `JSFunction` represents a JavaScript function
 - `JSArray` represents a JavaScript Array
-
+
+#### About Long Type
+Because there is no Long type corresponding to Java in JavaScript, the conversion of Long type is special.
+- Long value can be directly transferred from Java to JavaScript, which will be converted to Int64 bit。
+- To convert a value from JavaScript to Java into a Long type, you need to use the Double type, as shown in the following example:
+    ```Java
+    ((Double)target).longValue());
+    ```
