It is springtime in Beijing. Willows are spouting new life,jasmine tree lining city streets are a splash of yellow flowers and the harsh winter has given way to a gentle breeze.Stuck indoors for a bitterly cold winter ,urbanites are eager to get outdoors into nature ,and feel the sun again. Compare with the choking chaos in the heart of the city, suburban Beijing has clear air and more nature scenery. In the recent years,Beijingers have enjoyed driving out to the suburbs during the weekends with family members or friends, carming, climbing,fishing or just slightseeing. And spring is one of the best periods to escape from the city and head for greener pastures.
