The problem of parking Beijing's nearly 5 million cars is no less upsetting than traffic jams.

The Beijing government increased parking fee and launched a 100-day action plan from April 1 to regulate parking of cars. These are welcome moves because cars parked randomly on pavements and in bicycle lanes and even some motor lanes have been disrupting the movement of motor vehicles, cyclists and pedestrians alike.

Yet it is doubtful whether the 100-day action plan will help solve the parking problem once and for all, because the primary contradiction between lack of parking space and rapid increase in the number of vehicles can hardly be resolved in such a short time.
