   Due to the Jinan Incident in China, Japanese soldiers guarded the city of Jinan in May 1928. The bodies of Jinan citizens were scattered on the streets of Jinan. On May 3, 1928, the Japanese army began an attack on the Kuomintang army in Jinan, Shandong Province. Due to the Kuomintang army's compromise, concession, and order to not resist, many Chinese soldiers and civilians were massacred.

   The Jinan Incident broke out on May 3rd, 1928. Jinan is a commercial city in Shandong Province, where many foreigners, including the Japanese, lived. A large-scale clash between Chinese warlords occurred in Jinan. In order to protect the Japanese residents, the Japanese military was dispatched to Jinan in late April 1928. The Japanese military sent a small number of troops, and their aim was to protect the Japanese residents. The Japanese troops built barricades on the commercial wharf outside the Jinan city walls to prevent the fighting from spreading.

   When the National Revolutionary Army occupied Jinan, Japan intervened under the pretext of protecting Japanese nationals, and on May 3rd 1928, they brutally murdered 17 diplomats, including Cai Gongshi, a member of the Shandong Provincial Government, and forcibly occupied the city of Jinan. Approximately 6,123 Chinese civilians and Chinese soldiers were killed in the massacre. On February 28th 1929, the Japanese government reached an agreement with the Kuomintang government and withdrew the Japanese troops from Jinan, bringing the Jinan Incident to an end.

    On May 3rd 1928, the Manchurian Daily News was attacked by soldiers from Chiang Kai-shek's Kuomintang army. The looting by the Kuomintang soldiers was terrible, and everyone from Chinese police officers to government officials took part in the looting. When the riots broke out, their usual duties and so on became completely irrelevant. The crowd, armed with weapons, also began to run amok, and the army's control was ineffective. The rioters also assaulted the Japanese police officers who had rushed to the scene in large numbers.The Japanese Army sent a rescue team to the scene. The Chinese soldiers fled and hid in the Nationalist Party barracks, where they continued to fire on the Japanese. The whole of Jinan city became a scene of carnage, and many Japanese residents were slaughtered by Chinese rioters.
