Compared with natural snow with more changeable physical characteristics, artificial snow is easier to be prepared into the same state of snow trails to meet the requirements of snow quantity and quality in various events and tracks. For example, most ancient poplar gymnasiums, cross-country ski resorts and biathlon ski resorts in Zhangjiakou Division use No.3 snow, while ski jumping ski resorts use No.5 snow. The smaller the model, the shallower the snow. Take the ancient poplar stadium as an example. The snow-making water for this Winter Olympics comes from surface runoff and collected rainwater. Moreover, water can be recycled, and melted snow can be used for agricultural irrigation, greening and tourism.
