Sit in a chair or bed with one foot on the ground and the other slightly straight, and exercise your ankles and soles with breathing.

Do it with your feet 10 times (more than once).

Lift your left foot with your legs crossed and put it on your right thigh, and easily hold your left toe with your right finger as the standard. Then hold the upper part of the left ankle with your left hand to keep it still, and hold the forefoot of your left foot with your right hand, and rotate it left and right for 10 times, and then change it to your right foot.
