Living about 700 meters from the center of the Tianjin blast, Jiang Lingyu was injured by broken glass and passed out on Aug 12 at midnight.

But the second she was awakened by her husband, the 53-year-old asked whether her 10-month-old grandson was hurt.

While her son, who lived two floors below, was rushing downstairs with the baby, Jiang's husband, daughter-in-law and a neighbor carried her from the 29th floor to the ground. It was fortunate that her family was not severely injured.
