```Python
router.include_router(other_router)
```

The result is that in our app, each of the *path operations* from the `admin` module will have:

* The prefix `/admin`.
* The tag `admin`.
* The dependency `get_token_header`.
* The response `418`. 🍵

But that will only affect that `APIRouter` in our app, not in any other code that uses it.

## 在另一个 `APIRouter` 中包含一个 `APIRouter`

与在 `FastAPI` 应用程序中包含 `APIRouter` 的方式相同，你也可以在另一个 `APIRouter` 中包含 `APIRouter`，通过：

```Python
router.include_router(other_router)
```
