Being able to experience body painting and maintain it for several days without worrying about washing hands and losing it, nor worrying about keeping it for too long and affecting work and studies... This is the gradually emerging trend of Haina painting among young people. Easy to produce, personalized, and exotic, with an increasing number of fans, Haina artists engaged in Haina painting have become a new profession. However, the reporter found that this new fashion also carries certain risks. Haina painting has become popular among young people. Many women who travel to Southeast Asia have experienced Haina painting - an ancient body decoration art originating from India. Unlike traditional tattoos that people are familiar with, hand-painted Haina allows people to experience the same pleasure as tattoos in a short period of time without pain. College student Xiaoge discovered a booth surrounded by many people while playing outside, and found it to be a booth for "Haina Painting". She saw the vendor holding a "pen" that was as thin as a needle, squeezing and drawing, with the pen moving up and down. A pattern that was no different from the tattoo appeared on the customer's arm. Xiaoge has always wanted to experience tattoos, but for various reasons, he did not take action. After seeing Haina's painting, he couldn't help but experience it. "The painting looks very beautiful, and the merchant told me it will fade in 5 to 15 days. It's really impressive and suitable for a travel experience. A few classmates and I also want to try other styles in the future. In fact, there are many young people like Xiaoge who are willing to try Haina painting.". With a consumer base, some Haina teachers have also opened specialized stores. Ms. Wang, as a graduate of an art college, now not only does her job in her own studio, but also sets up a stall to paint Haina in her spare time. "At that time, there were no Haina paintings in the areas near us, but I was quite interested and went to learn more about them," Ms. Wang said. Out of her own interest and career sensitivity, she started self-learning Haina hand painting. The source of Haina dye is unknown and caution should be taken. This new thing, Haina dye, not only brings new fashion, but also brings new problems. During the interview, the reporter found that many Haina artists use extruded dyes that are mostly packaged in foreign languages, similar to ice cream barrels. Many painters are unsure of the specific materials inside. The reporter searched for the keyword "Haina Painting" on e-commerce platforms and received thousands of results, the vast majority of which were Haina Painting dyes. Although the prices range from a few yuan to a few tens of yuan per unit, the outer packaging of these dyes is also similar to the ones on the booth - there is no Chinese label or description of the composition of the raw materials. Some sellers, although claiming on the product page that the materials were made by themselves, are asked what they used but no longer answer. There is a certain risk of allergies in Haina Paintings. In fact, some people have already turned the fading Haina Paintings into "permanent tattoos" due to dye issues. When Mr. Wang was traveling in Bali before, he tried the local Haina painting. Shortly after returning to China, he found that the skin on his arm was itchy and peeling, thinking it was from the sun, but he didn't pay much attention. Later, the entire arm was red and swollen, and itchy. He immediately rushed to the hospital, only to find out that it was contact dermatitis caused by dye allergy in the painting. For this case, Chen Liuqing, the director of the dermatology department at Wuhan First People's Hospital, was interviewed by the media
