According to legend, Zhuge Liang became Liu Bei's corps commander, in charge of rations and taxes. Due to the large number of soldiers and horses of Liu Bei, the relative demand for grain and grass is large, and the burden on the people is even greater. For example, if people don't have enough food and warm clothes, their hearts will be unstable. On one occasion, Zhuge Liang was traveling incognito and saw a dish called "Man Jing". From the mouth of the old farmer, he learned that this dish is full of treasures, leaves and stems can be eaten, and the rest can be made into pickles. When the green and yellow are not connected, this dish can become a master dish. Zhuge Liang is very interested in this dish. He asked the old farmer about the yield and planting method of "Man Jing" per mu, and ordered the soldiers to reclaim land to plant this dish. On the one hand, it can supplement food rations, on the other hand, it can be used as livestock feed, which is both economical and affordable, killing two birds with one stone. So Zhuge Liang ordered the soldiers to plant "vines" widely, and there was enough rations. Later generations called this dish Zhuge Cai.
