Two or three days after I cut my double eyelids and took out stitches, several things like small blisters and small white chestnut rice grew on the wound. I was so scared. Why?

Well, if it's just white particles, it's scar hyperplasia, which will disappear with time. The same is true of my previous double eyelids, but if you have white blisters, it is infected. If you are infected, you should see a doctor. Usually, it can also be washed with sodium oxide injection (that is, physiological saline).
