Today, bitterness persists in China over the atrocities of the Second Sino-Japanese War and Japan's postwar actions, particularly the perceived lack of a straightforward acknowledgment of such atrocities, the Japanese government's employment of known war criminals, and Japanese historic revisionism in textbooks. In elementary school, children are taught about Japanese war crimes in detail. For example, thousands of children are brought to the Museum of the War of Chinese People's Resistance Against Japanese Aggression in Beijing by their elementary schools and required to view photos of war atrocities, such as exhibits of records of the Japanese military forcing Chinese workers into wartime labor, the Nanking Massacre, and the issues of comfort women. After viewing the museum, the children's hatred of the Japanese people was reported to significantly increase. Despite the time that has passed since the end of the war, discussions about Japanese conduct during it can still evoke powerful emotions today, partly because most Japanese are aware of what happened during it although their society has never engaged in the type of introspection which has been common in Germany after the Holocaust. Hence, the usage of Japanese military symbols are still controversial in China, such as the incident in which the Chinese pop singer Zhao Wei was seen wearing a Japanese war flag while he was dress for a fashion magazine photo shoot in 2001. Huge responses were seen on the Internet, a public letter demanding a public apology was also circulated by a Nanking Massacre survivor, and the singer was even attacked. According to a 2017 BBC World Service Poll, only 22% of Chinese people view Japan's influence positively, amd 75% express a negative view, making China the most anti-Japanese nation in the world.
