What are the ancient poems describing thoughts and regrets?

1, "Jiang Chengzi Mao Yi's Twenty Dreams in the First Month" Song Dynasty: Su Shi, original: ten years of life and death, not thinking, unforgettable. A lonely grave thousands of miles away, desolate and nowhere to talk about. Even if we don't know each other, our faces are dusty and our temples are frosty. At night, I suddenly dreamed of going home, and the window of Xiao Xuan was being decorated. Care for each other without words, only tears thousands of lines are expected to break the heart, and the moon and night are short and loose.

2. "Untitled time was long before I met her, but it was longer after we parted." Tang Dynasty: Li Shangyin, original work: Time was long before I met her, but it was longer after we parted, and the east wind rose and a hundred flowers blossomed. Silkworms in spring will weave until they die, and candles will drain the wick every night. In the morning, she saw her hair cloud changing in the mirror, but she bravely faced the cold of the moonlight with her evening song. There are not many roads to Pengshan. Oh, Bluebird, listen! -Give me what she said! .

3, "357 words/autumn wind words" Tang Dynasty: Li Bai, the original: autumn wind is clear, autumn moon is bright, the leaves are still scattered, and western Western jackdaw is surprised. The leaves in the wind gather when they gather. Western jackdaw has settled and the moon rises. Friends are looking forward to meeting, but I don't know where. At this time, on such a night, it is difficult to miss each other. When you enter my lovesick door, you will know that I am lovesick and bitter. Looking back, I am lovesick and infinite. If I had known this, I wouldn't have known him.
