How to solve the depth-of-field problem of "one object is clearly focused and other objects are blurred" in product photography

This is a typical background blur effect caused by shallow depth of field.

To make the product clear, use a small aperture and a short focal length, so that the parts that need to be clear are in the same focal plane, and the camera is slightly away from the subject when shooting. These are all ways to make the background blur effect not obvious.
