As heavy rain associated with Typhoon Dolphin continued to affect large parts of China, an increasing number of people were turning to immersive disaster simulations to experience extreme weather scenarios in a controlled environment at the Lvxing Disaster Simulation Training Center in Hangzhou, East China's Zhejiang Province.
At the country's first natural disaster simulation venue, adult participants pay 899 yuan ($133) per person to virtually confront situations such as typhoons, urban flooding and sudden flash floods, to gain a sense of what such emergencies might feel like.
Wang Kuanghan, operator of the training center, told the Global Times that the center is designed to allow people to experience the dangers of natural disasters in a safe and controlled environment, while raising awareness of the need to respect nature and avoid potential risks.
"We hope to pass on the experience we gained from encountering natural disasters during our years of traveling around the world," Wang said. "Beyond teaching people how to respond when natural disasters strike, what is more important is cultivating an awareness of how to avoid risks."
As of July, the center had received more than 70,000 visits this year for hands-on experiences, including tourists as well as companies and professional rescue teams that come for training. The number is higher than the same period in 2025, he noted.
Fu Minya, a Hangzhou-based office worker, told the Global Times that she has heard of the center and would like to give it a try.
"The frequent news reports of natural disasters in recent weeks have reminded people of how small and vulnerable we are in the face of nature's forces," she said.
After Typhoon Dolphin made landfall in China in early August, its remnant impact brought downpours to several provinces. Chinese authorities previously earmarked 80 million yuan to support flood and geological disaster relief efforts in the Central China's Henan and Hubei provinces and East China's Anhui Province, the Xinhua News Agency reported.
The flash flood simulation is one of the most intense experiences the center offers. Participants stand in a simulated river channel as an instructor presses a button, releasing around 500 tons of water from above. Within just three seconds, many participants are knocked off their feet, left tumbling in the rushing water and being swept toward the protective wall at the end of the channel.
"Real flash floods move even faster," said Wang. "When the water rises above knee level, it is almost impossible for an adult to remain standing. Many people instinctively think they should swim to escape, but that can be fatal."
Flash floods carry mud, branches and rocks that can quickly entangle your arms and legs. The right thing to do is to watch for warning signs of an impending flash flood, move away from the riverbank before the flash flood occurs, and quickly evacuate to higher ground on either side, he said.
In another exercise, several participants slog ahead holding each other's arms as the facility simulates winds reaching speeds of up to 165 kilometers per hour, as well as torrential rain.
However, there are concerns that simulated disasters could trivialize the suffering of disaster victims and turn the trauma of real-life disasters into entertainment.
This is a promising new niche in urban cultural tourism, Yu Jinlong, a Beijing-based cultural scholar, told the Global Times on Wednesday.
By striking the right balance between entertainment and public education while strictly adhering to safety protocols, such facilities can become more than just viral check-in destinations; they can serve as a replicable platform for public emergency education, Yu noted.
In the past, disaster-prevention education largely relied on display boards and lectures, which often made it difficult for people to develop an intuitive understanding of the dangers involved, Yu said.
Real-life simulations, by contrast, allow participants to experience firsthand the destructive force of typhoons and flash floods, turning abstract knowledge into tangible memories. This is where such facilities can offer unique social value, making them particularly suitable for educational programs for young people and emergency-response training for businesses and institutions, he said.
The experience can be impactful, but it should not be reduced to a sensationalist spectacle. Only by combining immersive experiences with practical self-rescue training and maintaining strict safety standards can this emerging model continue to serve as a meaningful platform for public disaster-prevention education, Yu noted.
Statistics show that 95 percent of people rescued from natural disasters survive through self-rescue, Wang said. "If you are swept away by water or hit by strong winds here, you will develop a much deeper understanding of how to respond to hazards and protect yourself."

原标题:今年中国已有7种高端钢材实现全新突破,面向新能源汽车、人形机器人等新兴赛道IT之家 8 月 24 日消息,据央视新闻客户端 8 月 22 日报道,我国钢铁产量连续多年位居世界首位。今年以来,钢铁企业依托全国重点实验室,聚焦高端特种钢材持续发力,不断实现核心技术突破,
一大批高端钢材实现了自主量产。钢材如何做到强度过硬,还能抵御海水腐蚀?在河北唐山的钢铁实验室,记者找到了答案。钢材加工过程中会产生易导致材料脆化的碳化物,科研人员通过调控钢材原子结构,将碳化物有效包裹。研究人员给记者算了一笔账,一台海上风电机要用钢数百吨,换上这种高性能钢,
钢板可以做得更薄,合金用量也大幅减少。如今,不只在海上,我国已经搭建起覆盖
深海装备、舰船制造、航空航天等多场景的高端钢材自主研发量产体系,从材料配方、轧制工艺到批量生产实现全链条自主可控。
IT之家从报道中获悉,这款我国自主研发的“蝉翼钢”厚度仅有 0.07 毫米,具备高强度、高延展性,达到全球精制钢顶级水平。

三 | 目前,这款钢材已广泛应用在集成电路基板、5G 基站信号接收器等多个领域。而在航空航天领域,新研发的低膨胀特种钢材已经投入大飞机复合材料成型模具生产。数据显示,今年以来,已有 7 种高端钢材实现全新突破,面向新能源汽车、人形机器人、储能装备等新兴赛道,多款专用电工钢、高强结构钢实现批量下线,为新兴装备核心部件提供材料保障。

四 | 目前,我国已有 3 家钢铁企业入选全球“灯塔工厂”,累计培育 36 家卓越级钢铁智能工厂、2 家领航级智能工厂。
