A public servant in a blue vest reminds people to stand on the right side of an elevator at the Chegongmiao Metro Station on Saturday. Nearly 50 civil servants acted as volunteers Saturday at 11 Metro stations on Line 1 to promote the civil behavior of leaving the left side of an elevator to people who need to pass through. Civil servants in the city have taken to the street 10 times to do voluntary work since Jan. 8 when the drive was launched. Zhang Xiaowei
