Look at Xin Qiji's first word, first from reality to memory, and then from memory to reality. This huge contrast makes the whole world more arrogant. Think about how you struggled to kill the enemy when you were young, in order to drive away the Jin people and recover the lost land in the north one day. It is this patriotic feeling that makes this poem even more precious.
Xin Qiji was very sad because of the collapse of the country. Even if he was drunk, he still didn't forget to recover the lost land in the north, so he got the opening sentence, "When drunk, look at the sword and dream of blowing the horn." "I was drunk and picked up the oil lamp beside me to look at my sword, but in my dream I returned to the battlefield in Ma Si. From this sentence, we can see what kind of mood Xin Qiji was at that time. His heart has been thinking about making contributions to the country and going to the front to recover the lost land in the north.
