What poses can a family of three take for a family photo without being rigid?

If you are in a studio, you can use dark brown tie-dye cloth, which has the texture of an oil painting. The pictures will be added later. Since there are a lot of people, chairs must be provided, the background must be large, and there must be a lot of light. In addition, the subject mentioned that there is a festival, so you can dress more festively and hold some holiday props in your hands, such as Lanterns, words like "福" and so on, it feels like it's there.
