In April, spring returns to the earth, and the snow in Northeast China gradually melts. Many ski resorts have closed down one after another, but the ice and snow economy has not pressed the "pause button". After entering spring, many indoor ski resorts in Jilin continue to attract visitors, while outdoor ski resorts are preparing to switch to summer mode. Various ice and snow laboratories are intensifying their technological research and development... From the consumer side to the supply side, Jilin is breaking down seasonal barriers and striving to achieve the transformation of the ice and snow economy from "one season hot" to "four seasons long red". The pure white snow trail winds and undulates, and skiing enthusiasts ride on snowboards with agile postures, galloping freely in a constant temperature environment of minus 6 degrees Celsius, feeling speed and passion. During the Qingming Festival holiday, Changchun Wanda Ski Resort became a popular check-in spot for many citizens and tourists. This 50000 square meter indoor ice and snow complex officially opened to the public in December last year and has received over 60000 visitors. During the Qingming Festival holiday, we experienced a peak in passenger flow. ”Meng Fanjuan, the head of the marketing department of Changchun Wanda Ski Resort, said, "In order to enable skiing enthusiasts to ski on high-quality ski slopes all year round, we increased the number of refrigeration machines running in spring and the frequency of snow making." Ski enthusiast Lv Kaiting from Changchun, under the guidance of his coach, just completed an independent ski run. This is my fourth time learning skiing here. I have already learned how to change blades smoothly, and there are places to ski in spring. It's really amazing. "At the Dajing Ice Base above the ski resort, the 1800 square meter international standard ice rink is also bustling. From beginners to professional athletes, the figures sliding, spinning, and chasing on the ice rink outline the vibrant sports scene in spring. The popularity of indoor ice and snow is a vivid reflection of Jilin's efforts to extend the ice and snow economy to all seasons. The outdoor ski resorts that have been gradually closed down have also entered a period of season transition and product upgrade. During the Qingming Festival holiday, Beidahu Ski Resort officially closed its doors after receiving the last group of skiing enthusiasts. After more than 160 days of operation, this ski resort received a total of 1.202 million visitors, a year-on-year increase of 13.9%; Achieved tourism revenue of 660 million yuan, a year-on-year increase of 14.2%. At Changbai Mountain Wanda International Ski Resort, some hotels are undergoing equipment maintenance and repair. The resort plans to launch sightseeing cable cars, hot springs, slides and other experience projects to provide tourists with vacation options and experiences different from winter. The "busy spring days" of the ice and snow laboratory are also laying a solid foundation for the "year-round prosperity" of the ice and snow economy. In the Key Laboratory of Culture and Tourism of Jilin University's "Ice and Snow Tourism Venue Equipment and Intelligent Service Technology", there are recently developed products such as skiing inspired penguins and indoor simulated skiing machines; In the Jilin Province Key Laboratory of Ice and Snow Sports at Northeast Normal University, ice and snow equipment such as youth racing skis and 3D printed crash helmets are displayed. In the future, we will continue to make good use of the 'industry university research application' research and development platform to conduct full industry chain research and production of ice and snow equipment, and establish a digital ice and snow equipment science and technology innovation demonstration center. ”Liu Junyi, director of the Key Laboratory of Ice and Snow Sports in Jilin Province, pointed to these equipment that have already been put into the market and said. From the popularity of indoor ski resorts to the iterative upgrade of outdoor venues; From the agile posture on the ice rink to the full investment in scientific research bases, relying on the unique ice and snow resources, Jilin is promoting the transformation of ice and snow fever from "single consumption" to "full chain development". Amidst the white mountains and black waters, the vivid scene of the ice and snow economy transitioning from "one season of fire" to "four seasons of red" is slowly unfolding. (New Society)
