Can I archive posts on WeChat Moments?

No, WeChat Moments does not have a built-in feature for archiving posts. Once a post is published on WeChat Moments, it will remain visible to your friends until it is deleted or until it is pushed down the timeline by newer posts.

However, you can still save or bookmark posts that you want to refer back to later. Here's how:

1. Long press on the post you want to save.
2. Tap the "Save to Favorites" button that appears.
3. The post will be saved to your "Favorites" folder, which you can access by tapping the "Discover" tab at the bottom of the WeChat app, then tapping "Favorites."

Note that this method only allows you to save individual posts, not entire conversations or timelines. Additionally, the "Favorites" folder is only accessible on the device where the posts were saved, so you won't be able to access them from other devices.
