 ### Data sharing
 
-The content of the same `cacheKey` is shared globally, which will bring the following features
+> Note: If no new request is issued, the "Data sharing" will not be triggered. `cacheTime` and `staleTime` parameters will invalidate "Data sharing". [#2313](https://github.com/alibaba/hooks/issues/2313)
 
-- Sharing request `Promise`, only one of the same `cacheKey` will initiate a request at the same time, and the subsequent ones will share the same request `Promise`.
-- Data synchronization. At any time, when we change the content of one of the `cacheKey`, the content of the other `cacheKey` will be synchronized.
+The content of the same `cacheKey` is shared globally, which will bring the following features:
+
+- Sharing request `Promise`: Only one of the same `cacheKey` will initiate a request at the same time, and the subsequent ones will share the same request `Promise`.
+- Data synchronization: When a request is made by one `cacheKey`, the contents of other identical `cacheKey` will be synchronized accordingly.
 
 In the following example, the two components will only initiate one request during initialization. And the content of the two articles is always synchronized.
