+You can use [include](https://docs.djangoproject.com/en/5.1/ref/urls/#include) 
+function for nested routings. This is similar as Django's URL routing system.

+Here's an example for nested routings. When you configure the routings in parent ``routings.py``;
+
+.. code-block:: python
+
+    urlpatterns = [
+        path("app1/", include("src.app1.routings"), name="app1"),
+    ]
+
+and in child ``app1/routings.py``;
+
+.. code-block:: python
+
+    app_name = 'app1'
+
+    urlpatterns = [
+        re_path(r"chats/(\d+)/$", test_app, name="chats"),
+    ]
+
+you can establish the connection via the path such like ``/app1/chats/5/``.
