Over half of Chinese learn about the War of Chinese People's Resistance against Japanese Aggression through national memorial days, an online survey indicates. 

Last year, China initiated two national memorial days to mark the victory of the War against Japanese Aggression and mourn those killed by Japanese troops during the notorious Nanjing Massacre. A grand ceremony, including a military parade, will be held at Tiananmen Square on Sept. 3 to commemorate the 70th anniversary of the event.

The survey, initiated by China Youth Daily, shows that 83.7 percent of respondents have learned about the war from textbooks, 70.2 percent from media reports, and 61.4 percent from movies or TV dramas.

Other sources of information include literature for 51.4 percent, older generations for 39 percent, museums for 33.6 percent, as well as schoolmates and friends for 12.9 percent.

Su Zhiliang, vice president of the Shanghai History Society, hailed the memorial days as an important part of China's modern state system.
