text: A 73-year-old woman died in front of horrified family members after she was knocked over by a Canadian tourist while visiting the Great Wall of China. Cui Hongfang, from Heilongjiang Province in north-eastern China, hit the back of her head on a corner of the stone wall after she collided with the 38-year-old Canadian woman. Police have ruled the tragedy an accident, although they are still investigating the circumstances of the Chinese woman’s death. Cui Hongfang's family told Chinese media that the Canadian tourist was running down steep steps . The victim’s husband told The Beijing News that his wife was knocked over as the tourist ran down steps on a steep section of the wall on Wednesday. He told the newspaper: ‘The foreigner was moving really fast. She was chasing [someone] and laughing and wanted to go between me and my wife.’ Mrs Hongfang’s family members said she lost conscious immediately, was bleeding from her mouth, nose and ears, and stopped breathing shortly after she was knocked over on the Mutianyu section of the Great Wall. They said the tourist ran further down the wall and then returned to the spot where the collision occurred. Police in Beijing have ruled Cui Hongfang's death an accident, although they are still investigating . Mrs Hongfang’s family called police and paramedics, who did not arrive until approximately one hour later due to the remote location north of Beijing. An official with the Mutianyu Great Wall Tourism Services Company told news website China.org.cn that the collision occurred in a ‘blind spot’ within the CCTV system, so there is no footage of it. The official said: ‘We have rules and warnings for tourists, asking them not to chase each other, run fast or play around on the steep sections of the Great Wall.’ Police decided not to charge the Canadian woman after interviewing her and witnesses. Mrs Hongfang’s relatives were not pleased that the woman has not been charged with an offence such as involuntary manslaughter, and investigators advised them to file a civil lawsuit against the tourist, who has since returned to Canada.
