David Kerr — the son of Lt. Donald W. Kerr, a U.S. Flying Tiger who was rescued by the Dongjiang Column from Japanese attacks in Dapeng in 1944 — shakes hands with a Shenzhen student portraying the Column’s Commander Zeng Sheng in a reenactment of Lt. Kerr’s rescue. David and his family first came to Shenzhen in 2008 on what he called a “journey of gratitude,” determined to fulfill his father’s lifelong wish to thank the Dongjiang Column for saving him. Since then, David has returned regularly to renew old friendships, retrace his father’s escape route, and help keep that history alive.       P4~5>Liu Xudong
