On the night of July 7, 1937, when the Japanese army was exercising near the Lugou Bridge in the southwest of Beiping, they asked to enter Wanping County to search under the pretext that a soldier was "missing", but the 29th Army of the Chinese defenders sternly refused. The Japanese then opened fire on the Chinese defenders, and then shelled Wanping City, and the 29th Army rose up to resist. This was the "77 Incident" that shocked China and the rest of the world, also known as the "Lugou Bridge Incident". 
The "77 Incident" marked the full-scale outbreak of the War of Resistance Against Japanese Aggression, and from this time, the Chinese people began an eight-year, arduous struggle against the Japanese invaders. During the entire Anti-Japanese War, because the Japanese army was significantly superior to the squadron in terms of equipment and military literacy, the squadron won less and lost more. However, although the equipment was inferior to the Japanese army, this did not weaken the determination of the Chinese people to resist Japan, and China did not lack troops that could fight, among them, the 74th Army was an army that could fight a tough battle with the Japanese army. 
The 74th Army, the full name of which is the 74th Army of the National Revolutionary Army, was formed on September 1, 1937 in the Songhu Battlefield, consisting of the 51st Division and the 58th Division (later supplemented by the 57th Division, a total of 3 divisions), the whole army has a total of 210,000 people. During the 8 years of the Anti-Japanese War, the 74th Army was the most brilliant unit, and there are countless wonderful examples. 
In the 1938 Wanjialing Campaign, the 74th Army as the core of the main force, to the Japanese army heavy casualties, the second battle of the first annihilation of the Japanese army almost a complete division of the good results, this battle did not have the advantage of the Pingxing Pass Eighth Route Army surprise attack, and did not Kunlun Pass ** firepower superiority, all relying on the bloody hard battle of the soldiers, the 74th Army can attack and defend, and the merit is great. In the Battle of Shanggao, the 74th Army annihilated 16,000 enemies, captured 2,800 horses, and killed one lieutenant general and one major general of the Japanese army. 
In the Battle of Changde, the 57th Division of the 74th Army faced tens of thousands of Japanese troops with 8,000 people, held Changde for 16 days, and stubbornly resisted the coordinated attack of the Japanese army's land, air and Tan. In the Battle of Xuefeng Mountain, the 74th Army as the main force, under the command of Wang Yaowu, almost completely annihilated the 116th Division of the Japanese Army, and eliminated about 30,000 devil soldiers. 
And the strong army is a famous general, and there are not a few famous generals who have come out of the 74th Army, including 5 former army commanders - Yu Jishi, Wang Yaowu, Shi Zhongcheng, Zhang Lingfu, Qiu Weida, which of these people is not famous? In addition, Li Tianxia, Yu Chengwan and other famous generals also served as division commanders in the 74th Army. (Note: The 74th Army was renamed the 74th Division during the Liberation War, but there were still more than 30,000 people in the division, and it was later destroyed in the Battle of Menglianggu, and Zhang Lingfu committed suicide.) ）
