It depends on what platform you collect square dance. If it is a square dance collected on the headline, you should watch the square dance video with your mobile phone. After watching the video, click a collection in the lower right corner, and the collection is successful. In "Configure Me", you can see the favorites bar and click it, or you can find what you watched before through the viewing record. The square dance collection is gone. Maybe the author deleted it, or you accidentally clicked the asterisk icon to cancel the collection. Well, of course you can't find it. Either you deleted it or you didn't collect it successfully. You can open the WeChat client first, then click my icon in the lower right corner, and then click Favorites.
