Poems describing war in the late Eastern Han Dynasty

(1) Cao Cao's ambition at that time was to unify China. (2) Battle of Red Cliffs, the result failed. (3) Cao Cao was able to win more with less in the battle of Guandu, mainly because he was good at employing people and adopted the correct advice of his advisers. Although Battle of Red Cliffs and Cao Cao were in absolute superiority in terms of troops, they were defeated because of pride and underestimation. This shows that pride goes before a fall. (4) Cao Cao was a famous politician, strategist and writer in the late Eastern Han Dynasty. At the end of the Eastern Han Dynasty, Cao Cao gradually expanded his military strength in suppressing the Yellow Scarf Uprising and became a warlord who occupied Henan. At that time, wars were frequent and production was seriously damaged. Cao Cao's construction of water conservancy in cultivated land in the north not only solved the problem of insufficient rations, but also played a certain role in the recovery of agricultural production. Cao Cao is resourceful, decisive and discerning. He used talents to welcome the Han Dynasty to offer the emperor to Xu, and his power was growing day by day. In 200, after the battle of Guandu defeated Yuan Shao, the Yellow River basin was gradually unified. In 208, he led the army south to unify China, but was defeated by Sun Quan and Liu Bei in the Battle of Red Cliffs, thus forming a three-point world. Cao Cao is also good at writing poems. Poems such as "A Journey in the Great Miles" and "Watching the Sea" express his ambition to innovate politics and unify the whole country, criticize the warlord's separatist struggle at that time, and reflect the tragic life of the people at the end of the Han Dynasty, which is magnificent, generous and sad.
