Private companies have been supporting China's 15th National Games, introducing innovative solutions aimed at ensuring a green, entertaining and athlete-friendly event. At an exhibition dedicated to the Games' zero-carbon initiatives, numerous supporting companies showcased a range of innovations. Among the highlights was a hydrogen-powered robotic dog that demonstrated its inspection and monitoring capabilities for the Games. Hydrogen energy is also utilized to secure the power supply for the competition venues. The country's first hydrogen emergency power vehicle, utilizing solid-state hydrogen storage technology, has been deployed to provide stable and clean energy support for the grand event. A mobile gaming company is boosting excitement for the Games by bringing experiences inspired by real events onto users' phones. Traditional Chinese medicine has also been incorporated into the event, helping athletes maintain peak performance. The 15th National Games will officially open Sunday across the Guangdong-Hong Kong-Macao Greater Bay Area city cluster in south China, marking the first time for the three regions to co-host the country's premier multi-sport event.
