Li He is a scholar, and his poems have long been famous. He could have learned to be an official, but this road to entry was ruthlessly blocked by the feudal ethics of "avoiding his father and taboo", which made him have no chance to display his talents. The word "why not" means that it is really out of helplessness. The word "take" in the second sentence, as easy as lifting weights, has the potential to break bamboo, vividly expressing the poet's desire to save the country. However, how easy is it to "gather 50 States in Guanshan"? Scholar's spirit can't achieve the great cause of recovering Guanshan, but if you want to get rid of the sad situation in front of you, you have to go through a military career and kill the enemy to make achievements. This contradiction highlights the poet's anger and injustice.
