How to change the tattoo symbolizing regret?

You can change it on the original image.

You can also mask the mode. It is generally recommended to go to a professional tattoo shop for modification or occlusion.

The earliest tattoo removal was to wash the tattoo with sodium nitrate, then smear it with turpentine resin and wrap it for 5 days. On the sixth day, puncture the tattooed skin with a pin, wipe off the blood with a sponge, sprinkle some salt on the wound, and then bandage it. Five days later, apply some medicine to the feather, and the tattoo will be removed within 20 days.
