2. 全诗 援琴怅独立，高月对秋堂。美人远于月，徒望空景光。坐忆执手时，七弦起凄凉。平生知音少，君子安可忘。客意如梦寐，路岐遍四方。日远迷所之，满天心暗伤。主奉二鲤鱼，中含五文章。惜无千金答，愁思盈中肠。此夕临风叹，零露沾衣裳。

2. The entire poem: With a lute in hand, I stand alone in sorrow, facing the high moon against the autumn hall. The beauty is far away from the moon, only longing at the empty landscape's glow. Sitting, I remember the time when we held hands, the seven strings evoke a feeling of desolation. Throughout my life, I have few true friends, how can a gentleman forget? The guest's thoughts are like dreams, roads diverge in all directions. The days grow distant, I lose my way, my heart filled with dark sorrow. The host serves two carps, within them are five articles. Alas, I have no thousand gold to repay, my sorrow fills my heart. This evening, I sigh to the wind, dewdrops soak my clothes.

12. Who could be the composer of this melody? It must be Qi Liang's wife!

The ancient melody of the precious zither, the red silk strings broken, knowing souls are few. The years slip by, and I age myself. The water is brimming over the bank, where can one find fragrant grass? The song of the Xiang Lai (an ancient poet) is not yet finished. The stone dragon dance is over, and the morning breeze from the pines is blowing.

35. 全诗淮南望江南，千里碧山对。我行倦过之，半落青天外。宗英佐雄郡，水陆相控带。长川豁中流，千里泻吴会。君心亦如此，包纳无小大。摇笔起风霜，推诚结仁爱。讼庭垂桃李，宾馆罗轩盖。何意苍梧云，飘然忽相会。才将圣不偶，命与时俱背。独立山海间，空老圣明代。知音不易得，抚剑增感慨。当结九万期，中途莫先退。

35. The entire poem gazes from Huaihuai to Jiangnan, facing a thousand miles of green mountains. I, weary from my journey, have half fallen beyond the blue sky. Zong Ying assists the strong prefecture, with land and water controlling the belt. The long river opens in the middle, flowing a thousand miles to Wu and Hui. Your heart is like this too, embracing all, great and small. With a pen, I stir up wind and frost, and with sincerity, I bind love. In the court of lawsuits, peach and plum trees sway; in the guesthouse, grand carriages are displayed. How unexpected that the clouds of Cangwu, drifting, suddenly meet me. Just as I was about to meet the sage, my fate is turning against the times. I stand alone between mountains and seas, aging in the sage's era. It's not easy to find a kindred spirit, and holding a sword, I feel more moved. When we should set a goal of ten thousand miles, don't retreat halfway.
