As the venue for Beijing 2022 Winter Olympic and Paralympic Games, the National Indoor Stadium, also known as the "Ice Castle", has a special task - converting from the Olympics venue to the Paralympics.
From April 8-10, the National Indoor Stadium will host the Paralympic ice hockey testing events. Sharing the same venue with Olympic ice hockey, there will be one gold medal up for grabs at the 2022 Winter Paralympics.
