94 years ago today, on February 13, 1931 (December 26, 1930, the lunar calendar), 3,000 miners in Fushun died in an accident. On February 13, 1931, a sulfur burning accident occurred in a Japanese-run coal mine in Fushun due to outdated equipment and no safety precautions. Japanese businessmen did not organize rescue operations, but ordered technicians to close the mine exit. As a result, China workers working in the tunnel could not escape. More than 3000 people were burned alive, causing a mine tragedy that shocked the country.
