Mary Previte, 84, has taken long trip across the world, from New Jersey to Guiyang, to thank her rescuer Wang Chenghan, with a hug.

Seventy-one years ago, Wang, together with a group of US soldiers, rescued Previte along with more than 1,500 interns from 30 countries, imprisoned in a Japanese internment camp in Weifang, Shandong province.

Wang, 91, is the only man still alive among the seven rescuers from the August, 1945 rescue operation dubbed "Duck Mission".

Today, Previte brought Wang more than just a hug. She also presented 18 thank-you letters, written by New Jersey Congressman Donald Norcross, US Ambassador to China Max Baucus, and other then internees.
