"Since 2009, I have visited the cemetery every May 12. Each trip to the cemetery and back home takes about a week. But we will come every year as long as we can walk."

Yao Denghui, mother of Teng Dengfeng, who was killed while rescuing people after the magnitude-8 Wenchuan earthquake five years ago, said while cleaning her son's tombstone at the cemetery of the May 12 earthquake victims of Yingxiu, Wenchuan county, Sichuan province, on Sunday.
