-Whether to use `resolve-url-loader` to rewrite urls.
+Whether to use [resolve-url-loader](https://github.com/bholloway/resolve-url-loader/tree/v5/packages/resolve-url-loader) to rewrite URLs.
+
+When enabled, `resolve-url-loader` allows you to write relative URLs in your Sass files that are correctly resolved from the current Sass file's location, rather than being relative to the Sass entry file (e.g. `main.scss`).
+
+If you set this option to `false`, the build performance will be improved, but Rsbuild will use the native URL resolution of Sass, which means all URLs must be relative to the Sass entry file.
+
+```ts
+pluginSass({
+  rewriteUrls: false,
+});
+```

+
+是否使用 [resolve-url-loader](https://github.com/bholloway/resolve-url-loader/tree/v5/packages/resolve-url-loader) 来重写 URL。
+
+当启用时，`resolve-url-loader` 允许你在 Sass 文件中写相对路径的 URL，这些 URL 会被正确地从当前 Sass 文件的位置解析，而不是相对于 Sass 入口文件（例如 `main.scss`）。
+
+如果设置为 `false`，构建性能会得到提升，但 Rsbuild 会使用 Sass 的原生 URL 解析，这意味着所有 URL 必须相对于 Sass 入口文件。

+```ts
+pluginSass({
+  rewriteUrls: false,
