Tattoos, commonly known as tattoos, are called nirvana in ancient classical Chinese. They use some tools to portray the ideal picture on people's monotonous skin, become the eternity of life, and keep the memories as the most beautiful picture in life. There are the following methods:

The first one was handed down by the Maori, tied with shark teeth and animal bone spurs, dipped in ink, and hammered into the skin with a small hammer.

The second is to tie several needles together and tie them to a wooden stick, and then artificially pierce the skin.

The third method is to use a motor to drive the needle into the skin. This method is commonly used by tattoo artists now.

Modern people's understanding of tattoos is all-encompassing and highly personalized. This slightly painful permanent pattern will accompany people's life. This kind of body language is commemorative, inspiring and liberating.

If Wen's back is washed away, the only way is plastic surgery. However, because the tattoo was originally caused by burning the skin with laser or medicine, no special medicine has been developed to repair it without leaving traces. The only way is plastic surgery.

From a medical point of view, tattooing is a harmful behavior. Skin is the first line of defense of human body, which can resist the damage of external mechanical, physical and chemical stimuli and the invasion of pathogenic microorganisms, and plays an important role in human health. Tattoos, on the other hand, destroy this line of defense, making the human body's ability to resist various stimuli decline, especially prone to bacterial infection.
