+## zh-CN
+
+通过语法糖的方式组织菜单目录树，在 `4.20.0` 之后推荐通过 `items` 属性实现。在下个大版本中语法糖用法将被移除从而让 Menu 可以获得更好的性能优化。
+
+## en-US
+
+Use the syntax sugar to organize the menu directory tree. We recommend to use `items` after `4.20.0`. In the next major version, the syntax sugar will be removed to make performance improvement be possible.
