I have encountered this problem before, and it is quite easy to solve it. Next, I'll tell you how to operate:

Tools: Xiaomi 1 1 Youth Edition, Little Red Book 7.80.0.

The first step is to click on me in the lower right corner of the home page of Little Red Book. (as shown in the figure below)

Step 2, click on the works under the notes column in the personal center. (as shown in the figure below)

Step 3, click the filter option on the note detail page. (as shown in the figure below)

Step 4, select appetite steaming in the filter settings. (as shown in the figure below)

These are all the steps of how to heat the air in the food pictures in Little Red Book. Remember to like it for me if it is useful to you ~?
