1937年，南京安全区国际委员会主要成员查尔斯·里格斯主动留下保护中国难民。86年后的今天，追随里格斯的脚步，他的曾外孙、美籍留学生克里斯·汉金(中文名：林奎)在南京寻访。寻访中，他更多了解当年南京安全区国际委员会成员对中国民众的无私帮助，真切感受到当年侵华日军南京大屠杀暴行对中国民众的伤害，也感动于这座城市、这个国家的人民至今对国际义士当年救助的深深感恩。历史依然鲜活(History is still alive)。

　　During the Nanjing Massacre, Charles Riggs, a key member of the International Committee for the Nanking Safety Zone, stood with the Chinese people and protected Chinese refugees.

　　86 years later, following Riggs' footsteps, his great-grandson Chris Hankin took a trip to explore Nanjing, in which he was appalled by the atrocities committed by the invading Japanese forces, but was more touched by the enduring gratitude from people in Nanjing and in China towards the international friends who once offered a helping hand.

　　From the trip, Chris found that history remains profoundly alive.
