Despite all the pain and suffering, stories are coming to us about the brave acts of rescue workers who've risked their lives saving others. They include a special team of divers, also dubbed ‘frogmen’.

On Tuesday, the second day after the capsize, a 65-year-old woman was rescued from the water. The same day, another 21-year-old sailor was saved.

The heros in these two rescue missions were 25-year-old Guan Dong and his colleagues.

"I remember the old lady very clearly. There were a lot of floating objects in her cabin. She was lying on a water pipe, with a torch in her hand. She started to cry as soon as she saw us. As for the young man, when I saw him, there was a dull look in his eyes and he didn't say anything. It seemed he had given up," Guan said.

Guan Dong is a navy officer with eight years of professional training.

He's a veteran who has been involved in rescues in dozens of disasters, but none have been as difficult as this one.

On Tuesday, he dove three times into the cold water, each time lasting over one hour.

But when Guan found the young sailor Chen Shuhan. Chen was too frightened to come out.

"As soon as I found him, I alerted people up on the water saying I found him. They said, 'Ok, talk to him'. I communicated with him for quite a while and told him there were people above water. I couldn't go out. I had to accompany him. If I left he would have been nervous," Guan said.

In the small space, breathing was difficult, and Guan made a courageous move. He gave his own professional equipment to Chen.

"There was diesel inside the cabin. When it touches water it evaporates and causes an allergic reaction to the eye. Breathing was difficult. He couldn't stand it. So I gave my mask to him to use before the other divers came," Guan said.

"He said, 'don't be afraid, we are with you'. Then they gave me a mask and put in an oxygen bag. I held the legs of the diver ahead me, and someone behind was pushing me out," Rescued sailor Chen Shuhan said.

But more danger lay furthur ahead. When he tried to come out himself, Guan met a whirlpool that dragged him 30 meters deep. And he was cut off from communication. He quickly let go of his heavy equipment and floated to the top.

"There wasn't oxygen in our tank after staying underwater for such a long time. "

"I thank brother Guan and the other divers so much...It was the rescuers that gave me today."

The actions of the rescuers will never be forgotten, especially by those they rescued.
