A retired Hong Kong businessman has donated more than 800 postcards and other artifacts from Japan's invasion of China in the 1930s and 1940s to the Shanghai History Museum.
Yesterday, Zheng Jiechu went to the museum to donate the fourth batch of more than 350 pieces. To date, he has donated more than 2,000 artifacts, including souvenir coins from Japan's occupation of China, since last year.
"Hopefully, my collection will help people understand how brutally Japan invaded China and treated Chinese people," said Zheng, 75, a time-long collector who was born in Shanghai.
Many of his donated postcards, which were issued by the Japanese government to celebrate its occupation in China, incorporated pictures taken by Japanese war reporters and cartoons by Japanese artists in China from 1937 to 1945. They include pictures showing local people forced by Japanese soldiers to bow at the entrance of the Waibaidu Bridge and a Japanese soldier shining his bayonet to kill Chinese civilians.
"I spent my entire childhood, from the age of 2 to 14, under Japanese occupation, and witnessed the killing of my grandmother, sister and brother by Japanese soldiers," he said, noting that his family was forced to risk the lives moving around the country - making stops in Jiangsu, Yunnan and Sichuan provinces - to escape persecution for more than a decade.
After moving to Hong Kong in 1977, Zheng collected various war-related artifacts through his friends in Hong Kong, Japan and Britain.
