Brocade Clothes Cover the Sun

Question: What is the distance from the junior captain of Jinyiwei to the commander? Answer: An embroidered spring knife. As a guard in brocade clothes, I should turn my hands to become clouds, cover my hands to become rain, and wear brocade clothes to cover the sky and the sun. PS: It's not Jin Yiwei of the Ming Dynasty. Because I don't understand it and it's too tiring to write about it, I just make up my name and replace Song Dynasty with Ming Dynasty. I don't know how to write upgrades, so please ignore personal force issues...
