    Shenzhen's fast development has made it become China's most crowded city! There are about 15 million people living on its 1,991 square kilometers. On each square kilometer averagely live 7,500 people. It is 1,080 more than that in Hong Kong, and nearly 800 more than that in Guangzhou.

    Besides. Shenzhen owns 2 million local vehicles, and about 300,000 vehicles from other places also run on the local roads every day. The total length of the city's road is 6,041 kilometers. It means each resident only owns 0.58 meters of road!
