BEICHUAN, Sichuan, May 16 (Xinhua) -- Thirty-three more survivors were pulled out of debris in Beichuan county in southwest China on Friday as rescue efforts entered the fourth day since the 7.8-magnitude earthquake on Monday.

The total number of survivors saved in Beichuan in Sichuan Province rose to 13,595, rescuers said.

Beichuan, a county of about 160,000 people, is one of the worst-hit region, with 80 percent of the buildings collapsed and at least 7,000 lives lost.

A 46-year-old survivor, Peng Zhijun, had lived on cigarettes, paper napkins and his urine when he was buried in the rubble in the past four days. He was still sober-minded almost 100 hours after the quake.

Doctors said he suffered bone fractures in the left arm and slight injuries in the legs, but the other parts of his body were basically in good condition.

"Natural disasters cannot be avoided. I had to save me from myself," Peng told reporters Friday evening.

He recalled that more than 10 people had been buried beside him in the rubble. "At the very beginning, they were all alive. But unfortunately, they died one after another."

"I had encouraged some of them to drink their urine. But they did not listen," he said.

Zhang Yan, a 36-year-old woman pharmacist, was rescued at 2:36 p.m. Friday. She was unconscious and soldiers carried her on their backs to a nearby medical center.

A 72-year-old woman named Deng Zhongqun was found by soldiers after being stranded at her badly damaged hillside house. She had been injured by a falling girder and had eaten only nuts over the past four days.

"Thank goodness for the soldiers. I only weigh 65 kilograms and they carried me by turns on their backs, walking miles to reach the medical station," said Deng.

The death toll in Sichuan alone exceeded 21,500 while 14,000 others remained buried as of 4 p.m. Friday, vice provincial governor Li Chengyun said at a press conference.

He said that 159,000 people were injured in the massive earthquake and 4.8 million people had been relocated.

Friday's death toll rose by about 2,000 from that of Thursday.

Sichuan had experienced 4,432 aftershocks in the past four days, Li said.

The national death toll from the earthquake rose to 22,069 as of 2 p.m. Friday, while 168,669 people were injured, the latest government statistics show.

In addition to the deaths in Sichuan, 364 were killed in Gansu Province, 109 in Shaanxi Province, 15 in Chongqing Municipality, two in Henan Province, one in Yunnan Province and one in Hubei Province.

The central government allocated another 1.17 billion yuan (167million U.S. dollars) to the relief fund for quake-hit areas on Friday. This brought the disaster relief fund from the central budget to 3.41 billion yuan.

Public donations in both cash and goods to the quake-hit areas rose to 3.175 billion yuan as of 4 p.m. Friday, according to the Ministry of Civil Affairs.

China has mobilized more than 130,000 troops for rescue operations, who were desperate to excavate survivors despite the passing of the prime time for survivors' rescue -- 72 hours after the quake.

Foreign rescue teams from Japan, Russia, the Republic of Korea and Singapore have arrived in Sichuan to aid the disaster relief efforts.
