Exhausted rescuers have pulled out more survivors on Sunday from the rubble left by the devastating southwest China earthquake on May 12.

Rescuers search for buried people at the rubble in the quake-devastated Beichuan County, southwest China's Sichuan Province, May 18, 2008. A survivor named Tang Xiong was saved from the rubble on May 18, 139 hours after being buried.

A woman named Yu Jinhua was saved alive around 8:10 p.m. Sunday from a flattened power plant in the Yingxiu Town of quake epicenter Wenchuan County.

"This is already a miracle. We believe she has been trapped more than 150 hours," said Lu Changchun, who came from Shandong and led the rescue operation.

A group of fire-fighters discovered Yu early Friday, but the rescue had been very difficult due to oddly misshaped structures on top of the woman and continuous aftershocks, Lu said.

"We had to be very careful and we tried five different plans. There was a dead body in the way, and her legs were already putrefied," Lu said.

Rescuers dug a five-meter deep whole to reach the woman, and had to amputate her legs before saving her.

"She was in a delirious state. She murmured she was already in a hospital and plead to stop saving her. We fed her milk and water, and her families were there to reassure her," said Ma Gang, another rescuer.

Yu has been taken to a nearby surgery.

Also in Yingxiu, a man named Shen Peiyun, 53, was rescued from his collapsed office building at 3:36 p.m. Sunday, after 146 hours in the rubble.
