0 1, Wei is located in the Central Plains, with a vast territory and rich resources. There are many Wei States in history, but the lack of food should refer to Cao Wei in the Three Kingdoms period. Throughout all the battles of Cao Wei, except for the shortage of food and grass in the early stage and the battle between Yuan Shao and Guandu, there was basically no shortage of food and grass in the later stage. One of the reasons why Cao Wei never worried about lack of food in the war was because of Cao Wei's geographical position. At that time, the Eastern Han Dynasty was divided into three countries, namely Shu Han, Soochow and Cao Wei. At that time, Shu Han occupied Sichuan and Shu, Wu Dong occupied Jiangdong, and Cao Wei ruled the north.
Cao Wei lived in the north, and most of his territory was in the Central Plains. In ancient times, the Central Plains can be said to be the gathering place of Chinese civilization. It is not only rich, but also has a large population. Among them, Jizhou at that time was known as the richest state in the world. In the battle between Yuan Shao and Cao Cao Guandu, Yuan Shao's food and grass basically came from Jizhou, in addition to Jizhou, there were many places such as Xudu, Xiapi and Chang 'an. Therefore, by contrast, Cao Wei is far richer than Shu Han and Wu Dong, and this grain is of course enough.
02. Cao Wei attaches importance to agriculture and logistics. Cao Wei has always attached great importance to farming, and since Cao Cao began to make a fortune, he began to encourage farming. At that time, one of Cao Cao's advisers suggested that Cao Cao encourage farming, recuperate and reserve enough food and grass. Later, both Cao Pi and Cao Cao attached great importance to this aspect. It is worth mentioning that Shu Han actually encouraged farming at that time, but the venue was relatively remote, so it was still not as good as Cao Wei.
Cao Wei's tax revenue is also relatively heavy. In Cao Cao's time, taxes were half. Although it gradually decreased later, it was still relatively heavy, which was one reason why Cao Wei was not short of food. In addition, Cao Wei also paid more attention to logistics. Cao Cao was able to defeat Yuan Shao in the battle of Guandu. A big reason is that Cao Cao burned his nest and Yuan Shao's food and grass. Therefore, Cao Wei's war has always been very effective in protecting grain and grass.
