What does Ai Qing's poem mirror mean?

The reflection of the plane, straight ahead, unabashed dodge, this is the truth. In front of it, anyone can see himself clearly, whether it's a drunken beauty or an old white hair. Because of this, some people find their own beauty and like it; Some people dare not look directly at themselves in front of it, avoid its ugliness, and even become angry from embarrassment. I can't wait to break it. The world is complicated, and the mirror may be naive, but it is serious and meticulously reflects the beauty and ugliness of life.
