There is such a city in China, according to historical records, the Mongolian Iron Horse took a full 36 years to defeat, and even the Japanese army in the modern Japanese invasion of China took 7 years to capture. This city is our Chongqing in China.
In 1243 AD, the Mongol army attacked the Song Dynasty in the south, the Mongol Khan planned to besiege Chengdu Chongqing, the military powerhouses of Deyang and Suizhong in Sichuan were lost, the Mongol army had surrounded Chengdu and was ready to take Chongqing together, while the defenders of Chongqing took the initiative to attack, supported Chengdu, set a trap ambush in Diaoyu City, and joined forces with the defenders of Chengdu to attack the Mongol army, this battle was surprisingly successful, not only the Mongol army was defeated, but also killed the Mongol Khan.
Directly led to the Mongolian civil unrest, this chaos is 20 years, Mongolia due to the great khanship dispute, Chongqing also spent 20 years peacefully. Until the new Khan successfully ascended to the throne, the Mongol army made a comeback, this time more ferocious, Chengdu fell directly, the army directly approached Chongqing, under the launch of the defending general Peng Daya at that time, the entire city military and civilians worked together to build a defense system, expand the scale of the city, and tenaciously defend diaoyu City. The Mongol army attacked for 16 years and ended in failure, and Chongqing remained undefeated.
Until 1279 AD, the Song Dynasty fell and the Yuan Dynasty was established. The Mongol army came to persuade them to surrender, and promised not to slaughter the city. The Mongol army attacked the city for 36 years and still stands here.
In modern times, in 1938, the Japanese army attacked Chongqing, and the defending general Hu Lian used his life to defend the city, and fought with the first gateway stone monument of the Japanese army in Chongqing, which was called the "Stone Pai Defense War" and was known as the "East Stalingrad Defense War".
After four days and four nights of holding the position, and no gunshots were heard in the last three hours, this was not a truce, let alone a rest, but the two armies of the enemy and us launched the most primitive, cruel, and bloody bayonet fighting to the death. The largest white-knife war of the Second World War broke out. After three hours of fighting without gunfire, the white-knife battle came to an end, the Chinese army's positions were not lost, and it was the Japanese who were defeated.
The war lasted until 1943, and for 5 years, the Japanese suffered heavy casualties and had to retreat. They then bombed Chongqing with aircraft, but they were unable to capture it. Chongqing, this tenacious city, represents the resolute and indomitable spirit of the Chinese people, and is a respectable city.
