The steps are as follows:

1. Take some food photos or record a short video to show the food feast and happy time when eating barbecue at the elder sister's house. When publishing a circle of friends, it is accompanied by a text description describing the mood and feelings of eating barbecue at the aunt's house, including the taste of food and the interaction with family or friends.

2. Add some related labels to the text, such as "barbecue" and "family dinner", so as to better organize and classify the content of friends circle. At the same time, add some appropriate expressions to make it more interesting and interactive.

3. When publishing a circle of friends, we should pay attention to protecting the privacy of individuals and others. If someone doesn't want to appear in the circle of friends, respect their wishes and avoid facial or personal information appearing in photos or videos.

4. Before publishing the circle of friends, make sure that the circle of friends is set to be public or visible only to specific people, so as to ensure that friends can see the sharing.

5. Click the "Publish" button to share your circle of friends with friends and followers, and you will be able to see the barbecue experience and interact.
