Tattoos (纹身) and body piercings (穿孔) have moved up on the trend list in recent years.

Around Western schools lots of teens are showing off new holes and “flesh ink” (纹身). As with all other subjects, the Chinese will surely have to deal with this situation with respect to their children. To get a better view of what has happened in the West, let’s sit down and hear what they say.

Tiara from Indiana:

I personally think body piercing is sickening. If there were supposed to be holes in your body, you would have been born with them. I do, however, think that ear piercing, is not wrong. There is a difference between ear piercing and belly button (肚脐) piercing. Ear piercing is not nearly as dangerous. I would be sick if someone stuck a needle in my belly button.

Lee from Illinois:

Hi! I live in Illinois. I am 23. I have 12 tattoos and three piercings. I love my tattoos and  consider myself an art collector. You would be surprised at who has given me the thumbs-up on  my art work. People on the street stop me to look at the tattoo on my leg. Most of them don’t  know what it is. They just think the work itself is great.

Subotai from Califomia:

I’m not against self-expression, but when I see high school students getting these piercing, I  really wonder. In some cases, the drive is deeper and darker than mere fashion. A friend of mine  tried piercing her own tongue with a safety pin. It got infected and she had a tongue the size of a  cow’s.

Jackson from Ohio:

I don’t think it’s wrong, but when people do it all over the place like their face and everything—I think that’s ridiculous (荒唐的). People who get the big dragons that cover their whole body—I don’t think that’s necessary. When I see naked chicks on guys, I think “You have no respect for women.”
