-In the above example, the callback event A will be replaced by the callback event B, the `key` of the callback event C is not repeated with others, and the callback event D is in another Activity, So the final callback events B, C, and D can all be created successfully.
+In the above example, although callback events A and B are callback events in the same Host App, their `key` is the same, so callback event A will be replaced by callback event B.
+
+The `key` of callback event C is not duplicated with others.
+
+Although the `key` of callback event D is the same as that of callback event C, their Host Apps are different, so they can exist at the same time.
+
+Callback event E is in another Activity, although the `key` of callback event F and callback event E is the same, but they are not the same Host App, so they can exist at the same time.
+
+In summary, the final callback events B, C, D, E, and F can all be created successfully.
+
+::: tip Compatibility Notes
+
+Setting the same **key** on different Host Apps in previous historical versions of the API would result in only the last event callback, but the latest version has corrected this problem, please make sure you are using the latest API version.
