The young man Wang Jun rushed into the office of Zhang Wanxia, director of the PLA 304 Hospital’s dermatology department, and said excitedly, “Auntie, I’ve been approved to join the army!” Wang Jun is a young man from Beijing’s Haidian District, wearing a green uniform and becoming a PLA soldier is his ideal since childhood. The year before last he signed up to join the army, and all the conditions are good, but I did not expect that the medical examination was brushed off because of a “eagle” tattoo pattern on the left arm. This “eagle” is his childhood curiosity, along with his neighbor’s brother together with the text, at that time quite proud, but also to show off a good deal to his friends. Who knows that when it came to the juncture of joining the army, this became a stumbling block. The doctor used laser technology to clean his tattoo pattern, and no traces could be seen. According to Director Zhang Wanxia, in recent years they have seen many young people like Wang Jun. They had tattoos out of curiosity when they were young, but when they joined the army, went to college, or looked for a job, they became troublesome and lost a lot of opportunities in choosing their future. There are also some girls who love beauty, in order to catch up with the fashion, tattoo eyebrows, tattoo eyeliner, tattoo lips, after a few years found that it does not look good, and then come to the hospital to ask to wash off. Director Zhang said that the tattoo is to pierce the skin with a needle, and then use a different color with the wound seeped into the skin, painted into different patterns. The pigment used is mostly black ink (carbon), usually green and black, but also other colors such as indigo, silver beads and vermilion. Tattoos are an artificial injury to the skin and are prone to local infections, such as skin tuberculosis, septic diseases, or keloids. Some people are allergic, tattoos can also cause allergic reactions, causing dermatitis and granulomas. Some clinics and beauty stores have very poor conditions, and even more than one person share a set of tools, and sterilization is not strict, serious cases can even cause a variety of blood-borne diseases, such as AIDS, hepatitis B, syphilis, etc. In the past, the elimination of tattoos generally used electrocautery, freezing, chemical corrosion or surgical excision, the patient is more painful, the effect is not very good, and will leave a scar. In recent years, domestic hospitals have introduced advanced laser treatment technology, no damage to the skin, the pigment fades quickly, and does not leave a scar, the effect is good. The director reminded the majority of teenagers, like tattoos such as the fashionable best not to catch, love beautiful girls want to tattoo eyebrows, eyeliner, must go to the regular hospital or beauty salon, not for cheap to those informal, poor conditions of the small clinics, and do not believe the advertising propaganda of those charlatans.
