After working as a slave for more than three years on a fishing boat, Sun Zhenglong jumped into the Pacific and swam six hours to freedom.

The 38-year-old with a full beard cried in his wife's arms after she hurried to a hospital in Lianyungang, Jiangsu province.

"I was desperate when I was trapped on the boat," Sun said. "I wanted to reunite with my wife and my son every single day."
