What is the fastest way to wash tattoos? How long will it take to finish washing?

China's tattoos are well developed. My friend went to Korea to wash it. I washed it twice. It's a little bright, and the fading is not obvious. The fastest way is laser. According to the principle that tattoos of different colors are absorbed, the tattoos are washed off. This needs washing several times. I want to be a literary and art soldier in the army. I washed once in Shangdu Temple in Dalian. My area is small, but it still hurts, and the price is a bit expensive, but it is very convenient to wash it once.
