-### If I want to replace the default language pack to reduce the size, how do I do?
-
-When the default language of your app is not **English**, you will be going to need
-to import another language file, which will increase the bundle size since you have
-both **English** and **Your desired language** bundled,
-you can use the plugin [NormalModuleReplacementPlugin](https://webpack.js.org/plugins/normal-module-replacement-plugin/#root)
-provided by [webpack](https://webpack.js.org) to replace the default language file,
-so that you will only get **1** language file bundled.
-Add the code below into your `webpack.config.js` to get it work.
-
-> webpack.config.js
-
-```typescript
-{
-  plugins: [
-    new webpack.NormalModuleReplacementPlugin(
-      /element-plus[\/\\]lib[\/\\]locale[\/\\]lang[\/\\]en/,
-      'element-plus/lib/locale/lang/zh-cn'
-    ),
