1. Lie on your back in bed. Support with your shoulders, hang your head over the edge of the bed, then slowly lift it up and then drop it. Repeat 10 times.

2. Without moving your shoulders, just stretch your neck forward as far as possible for 6 seconds, then slowly pull your chin down to your neck as far as possible, keep this action for 6 seconds, then relax and repeat it many times.

Method 2: practice chin-you can tighten your chin.

Shut up and move your chin as far as possible to the right. Also move left. Do eight groups at a time.

Method 3: grinding teeth-can eliminate the relaxation of neck and double chin.

1. Try to open your mouth horizontally and slowly to the bottom, and then stop 10 seconds.

2. Just close your mouth and grind your teeth hard, and don't stop hard 10 second. Repeat the above set of actions for 8 times.

Method 4: tongue exercise-make the lines of chin and neck more perfect.

As long as you move your tongue to the lower left, the muscles in your mouth will become hard.
