One 49-year-old passenger who survived the plane crash with only a back injury says he can't sleep, can't eat and cannot forgive himself. After the plane crashed, the man lost a female colleague on the plane, whom he calls Xiao Zou, amid the chaos. They were sitting in the front half of the plane and while he escaped through a broken window in the cockpit, she ran towards the back, which was on fire. Zou managed to escape but suffered third degree burns to 99 per cent of her body. 'I still don't understand why she ran to the back,' the man said. 'She must have been really panicked and not known what she was doing.' The plane was dark and full of smoke after the crash, and everyone was pushing in different directions. After he tried to kick open a window with a few other people, he discovered Zou had disappeared. After he finally escaped he saw Zou leaning against the plane. 'She was a good looking woman, and now she has not one piece of intact skin on her,' he said, tears welling in his eyes. 'She can still speak though, with a clear mind, but she's in such excruciating pain.' He said he had to drag Zou 20 to 30 metres from the plane by himself because there was no one else who could help. They come from the same village and have been business partners for more than a decade. Zou's family members were on their way to Yichun . Doctors have warned that she could die at any moment. He sat next to her yesterday as doctors inserted a drip. He fed her water with a cotton bud, fanned away the flies in the makeshift operating theatre and helped move her arms so she would feel less pain. 'I ran to the front, she ran to the back; but I'm fine, and she's not,' he said. 'I feel heartbroken.' His colleague was one of 12 patients transferred from Yichun to Harbin last night.
