Fujian's technology powers Winter Olympics

Zhu Chenye, vice-president of Anta, said the company has increased investment into developing Olympics equipment to "tackle key and challenging technological problems". The award ceremony costumes, for example, can keep athletes warm at -20 C, Zhu said.

The ammonia liquid separators used in the National Biathlon Center and the National Sliding Center in the Yanqing competition zone produce ice and maintain low temperatures at the racing tracks. They're a product of Snowman Group in Fujian.

The province supports the Games with over 30 technologies in various sectors such as equipment, souvenirs, venues, services and public security.

That also includes cold chain logistics ultraviolet light disinfection machines that can complete a disinfection within five seconds, robots measuring body temperature for participants and reminding them to wear face masks, as well as mobile nucleic acid testing laboratories.
