As we know, China is developing fast in science and technology.
Surprising robot
Can you imagine a robot swimming like a fish in the sea? A group of scientists at Westlake University in China have made one. Its name is Sea guru II. In March, 2025, the robot went 2,000 metres under the South China Sea successfully.
Smart Beidou
When you open a map on your phone in China, it is probably guided by the Beidou navigation Satellite System (BDS，北斗卫星导航系统). China started to build the BDS in 1994. It’s never an easy thing. Over 400 teams and more than 300,000 scientists have come together to solve big problems in building it.
Fast train
Do you want to travel on the fastest train in the world? The CR450 made by the China Railway Group is a new high-speed train that can travel at 400 km/h on average (平均). Its highest speed is 453 km/h. Before this, the fastest high-speed train in the world was China’s CR400. What’s more, CR450 stops quickly and makes little noise. It will further meet people’s wishes for a better experience.
