In many cases, you can. However, some platforms have restrictions on certain songs due to licensing and copyright issues. So, it's not always possible to use just any song you want.
It's quite simple. Just open the app where you want to add the song to your story, look for the option like 'Add Music' or 'Select Song', and then choose the song you like from the available library.
To put a song on your story, first check if the platform supports music integration. Usually, there'll be a feature like 'insert song' or something similar. Once you find it, browse through the available songs or upload the one you prefer. Just be cautious about any copyright restrictions.
If the GIF animation created by the fast hand was deleted from the user's fast hand collection, the trace of the GIF animation in the fast hand would disappear. Because Kuaishou was a social media application, GIFs uploaded by users needed to be stored on Kuaishou's server. If the user deleted the GIFs, their storage location on Kuaishou would change. Therefore, when the user viewed the GIFs on Kuaishou, their traces would disappear.
