Mother is holding a fragrant paper and doesn't know what to do. She asked me for photos in the back, looking silly.

Your mother either burns incense to worship Buddha or tells your fortune, but no matter what she does, I believe she is doing it for your own good, because only a mother can really be good to her children, and there is nothing wrong with satisfying them. After all, it's just a photo. Don't think too much, satisfy her superstitious heart. If she goes to get something back, or any news, she still has to believe it. These things cannot be explained by science.
