Residents remember foreign saviors in the city of refuge

People of Guizhou province remember the foreign doctors who came to China to save lives as the country defied Japan during World War II. Joseph Catanzaro and Zhao Kai report from Guiyang.

They ran into the night as the bombs continued to fall, the rattle of machine gun fire drawing closer as they made for the last train and their last chance of escape.

The news was passed frantically down the line of fleeing men, women and children: Changsha, the capital of Hunan province, had fallen.
