    The Auto Show, which is being held right now in Beijing, has risen to the top ranks of global auto industry events, as China has become the world's biggest auto market.For many Chinese youngsters, having a car has become a new lifestyle reflecting freedom and success
    First, there is the thrill of individual mobility and freedom, going from one place to another in their own time, and on their own terms.
    "I like the speed; I like the freedom; I can't imagine not having a car," Hou Mingxin, 39, owner of two cars, told the Financial Times.
    And these youngsters don't just want freedom through car ownership, but also a larger social circle.Thanks to the Internet, car owners can band together for leisure activities, such as going strawberry picking in the countryside.It is an activity that many car lovers would never have attempted without the benefits of a car.
    In China, the car is also a status symbol."It's an opportunity to declare personal success," said Michael Dunne, a Shanghai-based managing director of J.D.Power and Associates, an auto industry group."The small, environmentally-friendly models are not best sellers in China.The Chinese are crazy about big cars, a symbol of achievement," said Dunne.
    Thanks to a growing middle-class, and an increasingly developed network of roads, the number of car owners in China is rapidly increasing. China last year replaced the US and became the world's largest car market with 13.6 million vehicles sold.
    But the car craze(狂热) has raised environmental and traffic concerns. Many worry that car emissions could take pollution to a new level. Heavy traffic also troubles many Chinese cities.
    China is discovering the romance of the road just as developed countries seem to have lost it. “The younger generation in mature markets is unwilling to buy cars, especially in Europe and Japan," says Klaus Paur, of TNS Auto in Shanghai.
    In developed countries, owning a car can be expensive, with the parking fees car insurance and various taxes, said a 2008 article in US magazine Newsweek.
    "Having a car is so 20th century," Kimiyuki Suda, a young white collar worker from Tokyo told Newsweek.He mostly uses subways and trains."It's not inconvenient at all."
