After the visit of the Austro-Hungarian Emperor to China in 1934, Beijing began a large-scale reorganization of armaments and the relocation of arsenals, with the Jiangnan Manufacturing Bureau and the Jinling Arsenal moving to Chongqing, the Dexian Arsenal to Baotou, and the Fuzhou Mawei Shipyard and the Navy Arsenal to Qinzhou Bay in Guangdong. At the same time, the domestic army, including the local provincial armies, began to be reorganized, and the Military Training Department, presided over by Jiang Fangzhen, was in charge of the reorganization of the army and the training of military personnel.

Limited to finances, the Beiyang government's army was much smaller than it was during the Nanking government in another time and space, and since there was no civil war, the warlord power in the provinces was suppressed, and the Central Army remained at less than 50 divisions. In order to strengthen the management of the central authorities, the country was divided into seven major theaters: North China, Northeast China, Northwest China, Central China, East China, South China, and Southwest China, and a new round of adjustment and distribution of domestic forces began.

Yan Baichuan, who was like a tumbler in the political arena of the Republic of China, finally achieved positive results and became the commander-in-chief of the North China Theater, the commander-in-chief of the Northwest Theater was served by Wu Guangxin of the Duan department, the South China Theater was served by Ma Xiaojun of the Gui department as the commander-in-chief, and Jiang Yanxing of the Li department was appointed as the commander-in-chief of the Northeast Theater. After some contention in the Southwest Theater, the Duan Department finally gained the upper hand, and Jin Yunpeng, a senior general of the Duan Department, was appointed as the commander-in-chief of the Theater. The East China Theater was finally directly obtained, with Chen Guangyuan as commander-in-chief. The competition between the Li line and the direct line in the Central China Theater was fierce, and in the end, Wu Peifu, who was directly lined, became the commander-in-chief of the theater by virtue of his identity in Beiyang.

Contrary to the deployment of troops in another time and space during the War of Resistance, due to the capital in Beijing, North China and Northeast China were heavily armed, but the forces in East China and South China were relatively weak.

Since 1934, the five major arsenals in China - Linxian, Taiyuan, Baotou, Hanyang and Sichuan Arsenal have carried out large-scale expansion and fulfillment, of which the Hanyang Arsenal can produce 10,000 rifles and 300 artillery pieces per month, and the Linxian Arsenal mainly produces rifles and machine guns, with a monthly output of 12,000 rifles and more than 600 light and heavy machine guns, and the output of other arsenals is relatively less than half. Jiangnan Arsenal moved to Chongqing. Production has just resumed, but Qi Xieyuan, the governor of Jiangsu Province and the town's envoy, believes that Beijing is deliberately weakening his power and has been blocking the relocation of the Jinling Arsenal.

The invasion of Soviet Russia still caught the Beiyang government by surprise. A large number of troops began to assemble in Zhangjiakou, and groups of troops in full gear stood by on the platform of Zhangyuan Railway Station. Prepare for reinforcements north.

While China was urgently increasing its troops in Mongolia and Xinjiang in the north, Japan was brewing a major plan to invade China.

Under the planning of the Japanese Kwantung Army, the puppet Manchuria* provoked incidents in Xinmin in Mukden, Shuangliao in Jilin and Anda in Heilongjiang, but under the blows of the Northeast Frontier Army, the offensive of the puppet Manchu army suffered a failure and had to retreat to Mukden, Siping and Harbin.

In Japan, the Asahi Shimbun, the Tokyo Nikichi Shimbun, and the Yomiuri Shimbun are the three major newspapers. However, it was reversing black and white, hyping up that the Chinese side sent troops to attack Manchuria, which was repelled by the Japanese Kwantung Army and the Manchurian Army. The Japanese news media added fuel to the fire, which made the Japanese who were already full of aggressive ideas even more emotional, and in recent years, the Japanese Imperial Army fought a great war, and the Kwantung Army, which opened up territory for the empire in the Far East and Manchuria, has become a hero in the eyes of the Japanese people. Social groups in various localities have launched activities and petition rallies demanding that China be punished and that the military carry out "positive actions" to protect the lives and property of Japanese nationals in the Far East and Manchuria.

At the instigation of the War Department, Japanese Foreign Minister Hirota Hiroki had actually reached an agreement with Soviet and Russian Foreign Minister Molotov to divide up Manchuria and Mongolia. But now there is a strict divide between the government and the War Department. The Konoe Cabinet did not want to get involved in the "Shina War" too early, but the army hardliners, led by General Sugiyama Moto, advocated immediate mobilization.

The new Prime Minister of Japan, Fumiro Konoe, is a member of the Konoe family, the head of Japan's famous Five Regent Families, and is very respected in aristocratic circles. Members of the Konoe Cabinet include Admiral Sugiyama Moto, Minister of the Continent, and Admiral Mitsumasa Yonechi, Minister of the Sea. Foreign Minister Hirota Hiroki and Tibetan Minister Kaya are both veterans or authoritative figures of high moral standing in the Japanese military and political circles, especially Land Minister Sugiyama Mototo and Sea Minister Mitsumasa Yoneuchi, who are active army generals and navy generals and have high prestige in the army.

"Annexation of Manchuria" is a national policy that Japan has adhered to since the Meiji era, and it has never wavered or changed. Successive governments were divided into "progressive" and "radical" groups, with slight differences in the process of implementation. Japan had strongly supported the military junta in Canton in an attempt to provoke a civil war in China, but the return of hundreds of thousands of "labor legions" was indicated. The Beiyang government grew in strength and was eventually able to suppress the southern warlords. The "Canton Revolutionary Government" was finally dissolved, and the wishful thinking of the Japanese came to naught.

After Zhang Zuolin's attempt to bring the three northeastern provinces back to the central leadership. Under the planning of the staff officers of the Kwantung Army, such as Ishihara Waner, Seishiro Sakagaki, and Daisaku Kawamoto, the Japanese Kwantung Army and the Manchuria Railway Garrison Brigade took a risky fight, but on the contrary, Japan gained most of Manchuria, and the Kwantung Army suddenly became a hero in the eyes of the Japanese people, which further fueled the aggressive arrogance of the Japanese Army.

In cooperation with Soviet Russia, the battle plan for the invasion of Manchuria-Mongolia was facilitated by Ishihara's single-handed planning and operation.

Because of his outstanding contributions to the "Manchurian Incident," Ishihara Waner had a number of staunch followers in the army, including a large group of staff officers, including Seishiro Itagaki and Ninji Okamura, chief of staff of the Kwantung Army, Shozo Kawabe, chief of the Operations Section of the General Staff Headquarters, and Toroshiro Kawabe, chief of the Combat Guidance Section. In fact, due to the special structure of the Japanese Army, the command of operations is in the hands of these middle-level staff officers.

Ishihara's appointment as chief of operations at the General Staff Headquarters after the Manchurian Incident and his promotion to lieutenant general further encouraged the belligerent staff officers. During his tenure in office, Ishihara was responsible for formulating the "Outline of National Defense Policy" and elaborating operational plans for the invasion of all of Manchuria and Mongolia.

On the second day of the beginning of the invasion of Soviet Russia into the Far Eastern Republics, a joint meeting of the Five Ministers and the General Staff Headquarters was held in Tokyo. Ishihara resolutely supported the immediate start of war and cooperated with the Soviet army to carve up Manchuria. This proposal was strongly supported by Nagatsu Sabi of the Shina Division of the General Staff Headquarters, Akira Muto, Chief of the Operations Division, and Daisachi Tanaka, Military Division of the Ministry of the Army. However, Konoe decided that military operations should be postponed in view of the economic pressures in the country.

Konoe's decision was vehemently opposed by Army Deputy Chief of Staff Tada, who threatened to resign if the government announced a postponement of the war. This is actually threatening to dissolve the Cabinet as soon as the Secretary of War resigns. The Konoe cabinet had no choice but to announce its general resignation.

This is the party of the Japanese Army in disguised control of the cabinet since the 226 incident.

The Guards had to succumb to the pressure of the Army, and the Council of the Five Ministers soon made a decision to increase the number of troops in Manchuria, and at the same time approved the Navy's proposal to attack Shanghai and East China in order to win the "war" in order to match the Army's operational plan in Manchuria.

The Japanese government officially announced the increase of troops in North China, and when the news came out, the people in various parts of Japan were boiling, and people enthusiastically donated money to the army, and at the recruitment points in various parts of Japan, young people of appropriate age lined up in long lines, actively signing up to go to China to participate in the war, and "opening up the territory and establishing the industry" for the imperial country, and it seemed that victory was just around the corner.

Japan's warplanes have started
