The share-a-fact feature only excerpt the previous pare of the selected text, and it doesn't contain pictures of the page.
The process of my proposed feature is like this: When the user click the share button of a Wikipedia page, he can choose to share by links or share by image. Share by image would create a long snapshot-like image of the page's content

@Aklapper I'm sorry, I don't quite understand your meaning. You mean a usecase diagram?

@Aklapper Most of the Chinese users, whether they are editors or readers, may somehow have abilities to bypass the Great Firewall, whether via VPN or proxies, because it is the only way they can reach Wikipedia. (Especially the now heavily-censored Chinese Edition)
For the concern that the app itself would be blocked. Actually the entire Google Play Store services is blocked by the authority already, and most of Chinese Android users download their apps from the own store of the device's manufacturer (Huawei, Xiaomi, etc). And some of these manufacturers have already remove Wikipedia from its store. I would like to express that users of Wikipedia would find a way to get the app, whether genuine or pirated, if the app is blocked.
