438 years ago today, on January 25, 1587 (December 17, 1586 lunar calendar), the national hero Qi Jiguang passed away. During the Jiajing period of the Ming Dynasty, the people along the southeast coast of our country waged a vigorous struggle against the Japanese. The commander of this struggle was Qi Jiguang, a famous general and strategist. Qi Jiguang was from Laiwu, Shandong Province, and was born into a family of generals on November 12, 1528. Since childhood, he was determined to join the army, loved the military, and won the military. In 1553, he was sent to Shandong to undertake the heavy task of defending the Japanese from the sea, and later transferred to Zhejiang to guard Ningbo, Shaoxing, and Taizhou. After arriving in Zhejiang, he actively organized the new army and carried out strict training. He won the victory of Cixi and Taizhou, and completely wiped out the Japanese pirates who invaded Zhejiang. Later, the Japanese pirates went to the coast of Fujian to harass, and Qi Jiguang led his army to the front lines of resistance against the Japanese in Fujian and Guangdong. He led the army into the camp of the Japanese pirates, and took advantage of the enemy's unpreparedness to wipe out all the Japanese pirates. From 1562 to 1566, Qi Jiguang and Yu Dayou led the army to eliminate the Japanese pirates in the coastal areas of Fujian and Guangdong. In 1567, due to the southern Tatars in the north, Qi Jiguang was transferred to the north to train the border soldiers. For a total of 16 years, not only did the border area appear peaceful, but also the safety of the capital city of Beijing was also guaranteed. Qi Jiguang is not only a patriotic general with outstanding military achievements, but also an outstanding weapons manufacturing expert. He has many inventions in the military in his life, one of which is landmines. As early as 42 years ago in Jiajing, Qi Jiguang invented a kind of "wooden hair? FDDC? "'s firearms have injured hundreds of Japanese pirates. But this is still a weapon on the ground. The landmine buried in the ground was invented by Qi Jiguang at the age of 53, and it was called" self-perpetrating steel wheel fire "at that time. In April 8, Wanli, Qi Jiguang was the commander-in-chief of Jizhou, Yongping, Shanhai and other departments at that time. He was already the commander-in-chief of one side of the town and commanded more than 100,000 troops, but he still personally researched and improved weapons. Volume 12 of" Qi Shaobao's Chronology "contains: In order to prevent the invasion of Tartar and Duoyan and other guards, Qi Jiguang" Under the side platform wall, he chose the place where his flat and wide prisoners could be gathered, and dug the ground and buried the stone cannons inside. There is a wooden box in the middle, and the letters of each cannon are always in the box. And the bottom of the box is The Chinese-Tibetan steel wheel is also placed with flint next to it, and it lies on the ground. When the horse is captured, the steel wheel rotates, the fire comes out of the box, and the cannons are launched at the same time, so that the captor knows where he is. "The Ming Dynasty people buried this new type of anti-personnel weapon in the ground, which does not need to be manually ignited, and will automatically explode when the enemy steps on it. This is the earliest mine in the world. Qi Jiguang invented landmines in 1580, about 300 years before the Europeans invented landmines. In Qi Jiguang's life, more than 30 years were spent on the battlefield, and one-third of the time was spent on the battlefield of the Anti-Japanese War. This famous anti-Japanese general who fought in the south and north and risked his life to death was actually ostracized in his later years. In 1582, after the death of Zhang Juzheng, the prime minister of reform, opponents of reform in the imperial court became active. They slandered Qi Jiguang as an accomplice of Zhang Juzheng, spread rumors and slandered him everywhere. By this time, the northern border guards had been calmed down, and the Ming court transferred Qi Jiguang to Guangdong as a guard, effectively abandoning him. After years of exhaustion and mental depression, Qi Jiguang contracted lung disease. In 1585, he relapsed from the old illness and was allowed to return to his hometown to recover. He died in the early morning of January 25, 1587.
