September 22 is the World Car Free Day, initiated by France in 1988, aiming to enhance the awareness of environmental protection and the understanding of the harm caused the use of automobiles, and to encourage people in urban areas to take public transport, bike or walk.  Since then, this activity quickly spread across the world.  Today, environmental protection, advocating green transport, and developing energy-saving and new energy vehicles have become a global consensus.  Internationally, many officials and celebrities have also been using ecologically friendly means of transportation to advocate environmental protection.
