On the morning of Sept. 20, Zhang Xizhong received a call from the community director of the No. 2 community on Fushi Road in Tiancun Subdistrict of Beijing and was told that the drainpipe was locked up in Mr. Wang's apartment. In just half an hour, Zhang and two other helpers, all of them in army camouflages, arrived at Wang's apartment. After a while, they were able to dredge the drainpipe. " The veterans did an excellent job," said the staff at the subdistrict office in praise of Zhang and his team. [Photo by Dong Ning/China.org.cn]
