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."

二 |     8月25日消息，小米创始人雷军今早发文介绍自研芯片玄戒O100，这是一颗1.22TB/s高带宽的AI加速芯片，基于玄戒创新的高带宽矩阵总线，实现远超传统旗舰SoC的端侧AI性能。    雷军强调，玄戒O100未来将应用于手机、汽车、机器人等全生态品类。          玄戒O100是大模型专用的AI加速芯片，更是全球首款6nm 3D晶圆级堆叠的AI加速芯片。

三 |     通过先进的3D堆叠工艺，实现了1.22TB/s的超高带宽，这一速度是目前主流旗舰手机的16倍之多，可以让移动端设备的AI性能实现质的突破。

四 |     玄戒O100与玄戒O3是AI终端的“最佳CP”，最高可以实现本地AI推理速度高达330Tokens/s。          小米介绍，在传统计算架构下，计算单元与存储单元物理分离，数据必须在两者之间反复搬运。但内存数据通路受限于物理引脚数量，遇到了增长瓶颈。    当AI算力以指数级增长时，内存访问速度与算力之间已经严重脱节，成为性能的关键阻碍，业界称之为“内存墙”。         玄戒O100，则是小米“推倒内存墙”的破局之法，区别于以往晶圆→切割为裸片（Die）→逐片封装互联的方式，玄戒O100采用先进的Wafer on Wafer封装技术，也就是将多片完整的晶圆直接高精度对准与键合，继而再切割成独立的3D芯片。

五 |     这彻底摆脱了传统引脚数量对带宽的物理限制，将数据通路从“平面走线”变为“垂直穿透”，实现真正的近存计算（Near-Memory Computing）。          玄戒O100采用了先进的Hybrid Bonding混合键合工艺，摒弃了传统微凸点（Micro Bump）结构，直接将物理通路的间隔缩短至1.4μm，让数据通路密度大幅提升。     还采用了Face to Face（简称F2F）金属层直连结构，进一步缩短DRAM与NPU计算层的物理距离，让DRAM与NPU的金属走线“面面相对”，实现更短的物理互联距离，实现更快的信号传输。         此外，玄戒O100配备了14颗高算力NPU，通过玄戒高带宽矩阵总线，让数据可以在NPU与内存、与其他NPU核心之间等高速流转。
