After a high amputation on the spot where she was buried, Yu Jinhua, an employee of the Yingxiu Hydropower Company, was successfully rescued by the Shandong Public Security Fire Brigade at 20:10 on the 18th. Since the Wenchuan earthquake occurred until she was out of danger, Yu Jinhua had been buried in the ruins for 150 hours, and the rescuers spent as long as 56 hours in rescuing her.
