Is that possible to get realtime update for specific fan page?
I can get from user as long as it is allowed my apps. But how about fans?
Can send me some related documentation. If cannot, any optional I can use?

You need to create a Page and an App. Then the Page adds that App as a tab. Then you subscribe to Realtime-Updates for pages (instead of user) to get them.
To create an App: see FB documentation
To create a page:
www.facebook.com/pages/create.php
To add an App as a tab to a Page:
www.facebook.com/add.php?api_key=YOUR_APP_ID&pages=1&page=YOUR_PAGE_ID
To subscribe to an RTU for a page:
`https://graph.facebook.com/APP_ID/subscriptions?access_token=APP_ACC_TOKEN&object=page&fields=picture......`
Then FB will call your URL_CALLBACK anytime some page (that added you as a tab) has a change on one of the requested fields.
PS: I'm trying to subscribe to RTU for feed changes in the page, however according to the documentation is only possible to subscribe to picture :( If someone founds how to solve that, please let me know.
