0Employees of the Beijing Environment Sanitation Engineering Group have begun their annual assignment of sweeping up leaves that have fallen from trees around the city's streets, the Beijing Youth Daily reported.Each autumn, workers spend one month clearing the streets of fallen leaves, which the sanitation group allege contribute to the air pollution.Some residents oppose the cleanups on that basis that the golden leaves littering the streets make for a picturesque scene.At certain tourist spots, like the historic Diaoyutai State Guesthouse and its surrounding streets, the fallen leaves are allowed to remain.Related NewsAppreciating red leaves in early autumn2014-09-10People enjoy amazing autumn scenery in Beijing2014-11-02Catch the scent of autumn in Shixiang Lake2014-10-29Autumn scenery of populus euphratica forest in Xinjiang2014-10-27
