Analysis:
(Jin Zhongjing defended the war) In the first year of Aizong Tianxing (1232), Luoyang in Zhongjing was surrounded by Mongolian troops, and 2,500 people stayed in Zhongjing to hold on. He stood on the city with the flag of Chengsi, and his foot soldiers fought naked. Hundreds of brave men come and go to help, and the situation is like a tribe. When the weapon was used up, Meng Jun picked up an arrow, broke it into four parts and lit it with gunpowder. Soldiers also made a cannon, loaded with gunpowder, and fired marbles from a hundred paces away, which was very lethal and hit all the targets, causing the Mongols to be helpless and unable to get off the bus even when marching.
