First, read the English article below.

Tap the Facebook app icon, which resembles a white "f" on a blue background. If you're logged in, doing so will open your News Feed. If you aren't already logged into Facebook, type in your email address (or phone number) and password, then tap Log In. It's the bell-shaped icon at the bottom of the screen. This will open a list of your notification history. This will bring up the red Hide option to the right of the notification. It's to the right of the notification. Doing so will immediately delete the notification from this page; you'll no longer see it when you open the "Notifications" menu.  You can repeat this process for each notification you wish to clear. Depending on your version of Facebook, you may not be able to perform this process on an iPad. If so, try using the desktop site instead.
