At the beginning of the poem, I praised the sword: sharp sword, how pure and innocent I feel when you shine and wear you. An old friend thought I was alone and gave you to me as a friend. Your heart and mine are as pure as snow and as cold as ice. It expresses that poets and swords have the same thoughts and personalities.
In the middle of the poem, I swear with my sword: If it can't be used against those despicable people, my heart would rather rot and you will lose the meaning of existence.
At the end of the poem, the sword is called: Let's split the dark clouds in the sky and show Langlang Gankun. At that time, we can leave without regret and die a fair death.
