People put flowers in front of the tombstones of two martyrs during a ceremony in Pingxi Martyrs' Cemetery in Beijing's Fangshan district on Thursday. The two martyrs, Wang Hongchun and Liu Jianmin, both members of the Fangshan Blue Sky Rescue Team, fell into the water and lost their lives during a flood relief mission in Beijing on July 31. Liu and Wang were recognized as martyrs by the Beijing municipal government last year.
