Nanjing honors heroes of 'Hump Airlift'

A memorial hall in Jiangsu province is hosting an exhibition to remember the bravery and skill of pilots from China, the US and other countries who risked their lives to take part in the most dangerous airlift of World War II. Wang Xin and Cang Wei report from Nanjing.

Liao Yongbao was 64 years old before he learned the where-abouts of his father's grave. That was in 2004, when Liao, now 75, first saw his father's name engraved on a black marble tablet.

Liao Jingcheng, who was killed in aerial combat on June 18, 1941, when his son was just 10 months old, is buried at the Nanjing Anti-Japanese Aviation Memorial Hall, a complex in Zhongshan, one of the most picturesque areas of the capital of Jiangsu province, surrounded by trees and bathed in melodious bird-song.
