-We can also take advantage of the parent-child relationship between routes without needing to nest route components. This can be useful for grouping together routes with a common path prefix, or when working with more advanced features, such as [per-route navigation guards](../advanced/navigation-guards#Per-Route-Guard) or [route meta fields](../advanced/meta).
+我们还可以仅利用路由的父子关系，但不嵌套路由组件。这对于将具有公共路径前缀的路由分组在一起或使用更高级的功能时很有用，例如：[路由独享的守卫](../advanced/navigation-guards#Per-Route-Guard)或[路由元信息](../advanced/meta)。
