In the snow sports circle, many people call the ice skating rink "milk shaved ice". With food on one side and a hot sports field on the other, why are the two connected? In this regard, Gong Jun explained that because milk ice cubes are much softer than ordinary ice cubes, it can reduce the wear of the blade on the ice surface, so many skating rinks have been using this way of making ice before.

"But there are a lot of high-tech alternatives to this technology now," Mr. Gong said, "for example, the carbon dioxide transcritical direct-cold ice-making technology that China used for the first time [at the Beijing Winter Olympics], is very powerful." ”

It is understood that the four Winter Olympic ice venues such as the National Speed Skating Hall and the Capital Gymnasium all use carbon dioxide transcritical direct cold ice making technology, which greatly reduces the carbon emissions of the refrigeration process, which is also the first time that this technology is used in the Winter Olympics.

Finally, Gong Jun also gave foreign athletes Amway the food of the Winter Olympic Village- dumplings, "because the dumplings are very warm and delicious to eat, so that everyone can feel a warm Chinese New Year." (End)
