Zhuge Liang, the prime minister, inherited the legacy of Liu Bei, the former emperor, and assisted Liu Chan, the young master, to govern Shu. In the face of great pressure and threats from home and abroad, Zhuge Liang, after carefully analyzing and studying the internal and external situation of Shu, thought that to realize Liu Beidong's ambition of rejecting Dongwu, destroying Cao Wei in the north and unifying the whole country, it was imperative to fix the internal affairs first. He chose the policy of taking care of the people at home and renewing the alliance with Soochow abroad. After nearly two years' efforts, the domestic order of Shu is orderly, the people's hearts are stable, the national strength is enhanced, and the internal political power is further consolidated.
In the third year of lite (AD 225), Zhuge Liang saw that the time was ripe to solve the "internal worries", so in the spring of this year, he led an army south, killed Gao Dingyuan, the "Yi Shuai" who happened in Yuegang County (now Xichang), and kidnapped Prince Meng Huo of Yizhou (now Jinning, Yunnan) who sent Wu Dong.
Zhuge Liang personally led the army of the West Road from Anshang (now pingshan county, Yibin) to Yuegang County along the waterway of Shui Sheng (Jinsha River) and defeated the rebels in the battle of Yuegang. After Zhuge Liang beheaded Gao Dingyuan, the leader of the rebel army, he continued to lead the army south and launched a crusade against Meng Huo, who was entrenched in Nanzhongyizhou. The army crossed the Lushui River from Gudukou (now Huili County) without joining forces. At this time, the prime minister's army has traveled thousands of miles, exhausted all the way. In addition, the front line is too long, the logistics supply is difficult and the climate is hot. When the meat reached the front line, it was rotten and inedible, which led to the deterioration of soldiers' physique and the decline of combat effectiveness. Zhuge Liang was very anxious about this, but he couldn't think of a good way at the moment.
One night, Zhuge Liang walked out of the Prime Minister's mansion with two bodyguards anxiously, and unconsciously came to a local indigenous family. When the host saw a distinguished guest coming to the door, he asked his family to put wine and meat on the table to entertain the Prime Minister. Zhuge Liang picked up a piece of meat in the bowl and chewed it slowly in his mouth. This meat is not fresh, but it tastes delicious and has a lasting fragrance. Zhuge Liang was surprised and asked how it was done. How long did it last? The shopkeeper replied that it was invented by local people and called oily meat, which has been stored for more than a year. Hearing this, Zhuge Liang cheered secretly, got up and dragged the master and said, "Let's go to our army tent and teach the military chefs to cook oily meat." In this way, Zhuge Liang inadvertently succeeded in finding a solution to the nutritional supplement problem of soldiers in the army, restored the combat effectiveness of the troops and the physical fitness of the soldiers, and left a beautiful talk of Meng Huo's "seven escapes and seven verticals" in his later battle with Meng Huo.
The following autumn, Zhuge Liang completely won the victory of pacifying South China. After the troops returned to Korea, every time they mentioned the people's oily meat, they always praised it.
Nowadays, the people of Yanbian, who live in beautiful scenery, not only bring the oil bottom processing technology invented by their ancestors to the extreme, but also push it to the market and register a trademark, which has become the first choice for many tourists visiting Panzhihua to give gifts to their relatives and friends.
