Safe Streets without Ice and Snow

An snowy and icy world is always seen in fairy tales, reprenting holiness and purity. However, it might also be a troublesome event in the real world, causing traffic jams or even injury to citizens. Shenyang is just a city where snow and ice causes troubles during the winter time. In order to reduce the lagtime of traffic and recover the streets to safety, each winter Shenyang Kejing organizes it staff to sweep snow and ice on road close to the factory.
