Jia Dao's swordsman in Tang Dynasty.
After ten years' hard work, I have grinded out a sword. The edge of the sword flashes in cold light, but I haven't tried its sharpness. Now take it out and show it to you. Whoever is wronged may as well tell me the truth.
Translation:
After ten years of grinding a sword, the blade is cold and shiny, but it has not been sharpened. Now show it to you. Who has any grievances?
"Ten years to grind a sword", the swordsman painstakingly polished. The profile shows that this sword is extraordinary. Then, be positive: "Frostblade has never tried." Write this sword, Bai Rushuang, with cold light. It's an extremely sharp sword that hasn't been sharpened.
To say "I haven't tried" is to be eager to try. Now I'm going to meet a "gentleman" who knows virtue and good deeds, so I confidently say, "Let you see who is unfair today?" Take this sword out for you today, and tell me, who has grievances in the world? A kind of ambition and lofty sentiments eager to display their talents and do something.
Obviously, "swordsman" is a poet's metaphor, and "sword" is a metaphor for one's own talent.
The poet did not describe his ten-year career of studying hard at a cold window, nor did he express his outstanding talent and grand ideal. But through clever artistic conception, I integrate my thoughts into the images of "sword" and "swordsman". This way of expressing political ambition with vivid images is really ingenious.
