1562, Qi Jiguang was ordered to lead his division to rescue Fujian from Zhejiang. Unexpectedly, on the way to March, the troops were led into a fork in the road, the road was narrow and difficult, and the team was caught between Scylla and Charybdis. Although they won the battle, they suffered heavy losses. Then Qi Jiguang, full of grief, led down archers back to Zhejiang. At the end of the following year, a Beijing army rushed into Qi Jiguang's army account with an urgent imperial edict. Qi Jiguang listened to the divine mandate.
It turned out that after Qi Jiajun left Fujian, the enemy made a comeback and gathered more than 6,000 people to surround Xinghua Fucheng. Liu Xianfeng, commander-in-chief of Guangdong Province, ordered troops to reinforce from Fuzhou and sent eight soldiers to contact Fucheng first. Eight people were killed by Japanese pirates on the road. The enemy took off their clothes and put them on themselves. They sneaked into the city with forged letters from Liu Xian and occupied Xinghua House from the inside. The imperial court was shocked, so it was sent to Fujian as the company commander, Tan Lun as the governor of Fujian to preside over the anti-Japanese military, and Qi Jiguang was ordered to reinforce quickly.
Qi Jiguang frown. In addition to the serious shortage of troops, it is urgent to get in touch with the two ministers first. However, the enemy was treacherous and cunning, and set up a series of tricks to trap the Ming army in a passive position. In view of the previous two painful lessons, how to ensure the safe delivery of letters has become a stumbling block in front of Qi Jiguang. He is in a hurry and can't do anything.
New Year's Eve passed quickly. On this day, Qi Jiguang rode a horse to inspect the situation of recruiting new soldiers. When he lowered his head and raised his eyebrows, a long rope crossed his nose. Qi Jiguang reined in and realized that it was the people in the city who were preparing riddles for the Lantern Festival. He was thoughtful, and suddenly his eyes lit up and his plot succeeded.
When he arrived at the recruiting office, Qi Jiguang immediately ordered people to write two poems with pen and ink. One song is: "Liu Bian strives for low gas, Berta strives for the sun. Meng Ying said happily, clap her hand and tell you. " Another song is: "Spring flowers are blooming, autumn mountains are blooming, guests need to sing in golden cups, and solitary lamps burn silver pots." In the eastern suburbs, crossing the West Bridge, the first day is urged by the sound of chickens, and bells are set to cover ditches. "Then he wrote a letter with numbers to Tan Lun, and respectively. He asked several intimate followers to engrave these two poems in their minds. After they disguised themselves, they quickly sent the letter to the adults.
After receiving the letter, the three generals were overjoyed. They exchanged messages with letters of the same number, and made intensive arrangements while waiting for the arrival of Qi Jiajun. 1April 563, Qi Jiguang led the troops to the East Pavilion of Xinghua City. As the main attack in the middle road, he attacked the famous mountain department on the left and the Xiushan department on the right, annihilated the enemy who occupied Xu CuO in one fell swoop and rescued more than 3,000 prisoners. Since then, the plague in Xinghua has been eliminated.
What does a letter with only numbers have to do with these two poems? It turns out that Qi Jiguang used these two poems for the first time in human history to create the anti-tangent code of military intelligence. He took the first letters of the first 15 words of the previous poem and numbered them from 1 to 15. Take the 36-word vowel of the last poem and number it as 1 to 36; Then number the eight tones at that time as 1 to 8 in sequence. In this way, a complete "arctangent code" system is formed, such as the number 5-25-2, which is cut out as the "enemy". He asked the messenger to remember the poem and read it to the three generals face to face, considering that even if the letter fell into the hands of the enemy, they would never have thought that such a pile of numbers would be a military letter.
After that, Qi Jiguang specially compiled the Eight Tones Meaning Manual, which was used to train professional intelligence personnel and signal soldiers, and played a decisive role in the military development of China and even the world.
