China hired a company called TechnoAlpin to create the snow.TechnoAlpin created man-made snow at several earlier Winter Olympics.For the snow in this year's Olympics,TechnoAlpin laid over 40 miles(64 kilometers)of pipes and brought in hundreds of snow-making machines.With all equipment,making the snow for this year's Games took seven weeks.
