First, read the English article below.

Using warm water and soap, apply a washcloth to gently wash out your new piercing. Keeping dirt, grime, and bacteria away from the wound should be enough to prevent infection.  Be sure to clean the piercing after exercise, going outside, cooking, or cleaning. Rubbing alcohol, though it kills bacteria, will dry out your skin and potentially cause an infection. While you could buy saline at the piercing parlor, you can also make it at home with only 2 ingredients. Mix 1/8 tablespoon of non-iodized sea salt into a cup of distilled water and stir until it dissolves. Submerge your piercing in the saltwater, or soak a clean cotton swab in the water and apply it to the piercing for 20 minutes twice a day. Dirty hands are the number one cause of infection, so always wash your hands before touching or treating your piercing. If you have a piercing that is constantly rubbing on your clothes, wear looser clothing. This is especially true for navel, genital, nipple, or other body piercings. These places are hot-spots of moisture and bacteria that commonly lead to infections. Your piercing is an open wound and it will absorb bacteria much more readily then unbroken skin. Don’t freak out if you see redness or soreness in the first few days after a piercing. This is your body’s normal response to a puncture. Inflammation is common and can be easily treated with an ice-pack and ibuprofen. If the inflammation lasts for more than 3-5 days, however, you may be developing an infection. While it may seem counterintuitive, you should avoid removing the jewelry if you notice signs of active infection, such as pus, since removing the jewelry can cause the piercing to close up and trap the infection inside your body. It's important that the piercing remain open so that it can drain; otherwise, you may develop an abscess or worsen the existing infection.
