What is the difference between Cao Wei and Shu Han in the Three Kingdoms period?

The difference is that Cao Wei cultivated land internally, while Shu Han cultivated land externally.

When Cao Wei settled the fields and Cao Cao raised soldiers, for military reasons, Cao Cao was very much looking forward to this idea of the integration of soldiers and agriculture. Later, after taking root in Xuchang, he carried out land reclamation experiments in Xuchang area outside the ruling area. After success, he immediately set up a special captain to carry out precise management. Later, he transplanted flowers into the economy, making it an important means to quickly restore the local economy after attacking the city.

Cao Cao's method of land reclamation has a low cost and can accurately obtain enough military food. After the scale of reclamation was expanded, the reclamation of Cao Wei gradually evolved into another form-immigration reclamation, which developed faster and on a larger scale than that of sergeant reclamation.

Therefore, Cao Wei extended the reclamation of the sergeant to the economic level, so the reclamation system of Cao Wei was very important for the later restoration of agricultural production.

In fact, the original intention of reducing commissary consumption only happened in the early stage of Cao Cao's development, so that the north was unified later, and then his son established Cao Wei, taking the increase of commissary as extra income, and Cao Wei, who occupied the north, was no longer so short of commissary. Under the vast territory of the Li people, color really needs large quantities of food.

Besides, the reclamation of Shu mainly refers to Zhuge Liang's reclamation strategy during the Northern Expedition. As we all know, the national strength of Shu is very weak, so it is inevitable to transport grain to the front on a large scale, which is a waste of people and money. The northern expedition is far away, so from Chengdu to Hanzhong front, water transportation is basically not considered, only land transportation is feasible.

As we all know, it is difficult to get through the Shu Road and get into the sky. Therefore, if the grain needed for the Northern Expedition is honestly sent from Chengdu to Hanzhong, if it reaches this intensity, the terrain will be temporarily limited, which will lead to the risk of famine in the base camp there as soon as the grain is delivered here. This is undoubtedly a great disadvantage for the Shu-Han regime, which concentrated on the Northern Expedition to recover the Han Dynasty. But who is Zhuge Liang? In this case, he immediately gave his own solution, that is, reclamation.

It can also be seen that Shu and Han cultivated land for the army, while Cao and Wei cultivated land for the people.
