Into the city, it is looking around the depression, cold water from the blue, the twilight gradually rise, the garrison corner sad chanting. I have pathos, feeling the present and the past, because of this song. The old man thought that there was a "Kibi" of sadness. HuaiZuo famous capital, bamboo west good place, saddle less in the first trip. The spring breeze over ten miles, all the chestnut wheat green. Since the horse peeped into the river to go, the waste pool trees, still tired of talking about soldiers. As dusk falls, the clear horn blows cold, all in the empty city. Durang Jun reward, counting now, to re-arrive to be surprised. Even if the cardamom words, the green house dream is good, it is difficult to assign deep feelings. The twenty-four bridges are still there, the center of the waves is swinging, and the cold moon is silent. I think the bridge red medicine, year after year to know who is born.
