111 years ago today, on December 11, 1914 (October 25, 1914 in the lunar calendar), the Japanese cabinet passed the "Twenty-one Rule" against China. The Japanese army entering Shandong is wantonly trampling on China's land. On December 11, 1914, the Japanese cabinet passed the "Involvement in the Case with China," or the "Twenty-one Articles". On the 2 of this month, it was submitted to the Emperor for approval, and immediately summoned the Minister in China to return to China to report his duties. In addition to the "21 Articles", the Japanese government also attached matters that Japan can guarantee to China during negotiations. The main points are the following four points: (1) Guarantee the status of President Yuan Da and the safety of his family; (2) Strictly ban the Revolutionary Party and China students studying in Japan, and pay full attention to the anti-Yuan Japanese businessmen and bandits;(3) Discuss the issue of the handover of Jiaozhou Bay at an appropriate time;(4) Consider reviewing the matter of honoring or presenting honours by President Yuan Da and relevant senior officials. The Japanese envoy Rizhiyi also proposed adding means of oppression or temptation, such as: retaining the Japanese army stationed in Shandong and occupying the northern section of Jinpu Road if necessary; inciting the Revolutionary Party and the Zongshe Party to engage in activities to subvert the Yuan government; In response to the financial difficulties of the Yuan government, it plans to use loans as bait, etc. On December 15, Rijiyi returned to Beijing and secretly engaged in negotiations and arrangements.
