What are the poems that are very disappointed, sad and chilling?

1, if I had known it was so frustrating, why didn't I know each other at first?

Li Bai said it in the Tang Dynasty.

I wish I didn't know you then.

2, lying in an empty bed listening to the rain from the south window, who will burn the lamp to mend clothes at night.

Song Hezhu's "Partridge Sky, Re-crossing Changmen, Everything is Wrong".

Lying in an empty bed, listening to the biting wind and rain outside the window, who will burn the midnight oil to mend my clothes?

3, tears on the pillow, dark heartbroken between flowers.

From: Send a Gift to the Neighbor's Daughter/Send a Message to a Member by Yu in Tang Dynasty.

No matter when sleeping, or when Shang Huashi is sleeping, he will secretly cry, crying deeply.

4, red beans are unsightly, full of acacia tears.

From: The Five Dynasties Niu Xiji's "Crescent Moon with Fine Eyebrows and Beautiful Eyes".

I can't bear to look at red beans, and my eyes are full of acacia tears.

5. This past year should be a wonderful time. Even if it is full of emotions, who can enjoy it together?

Liu Yong in the Song Dynasty said, "Lin Yuling is chilling and sad".

It's been a long time. I guess even if we meet fine weather and beautiful scenery, it's just like nothing happened. Even if there is full affection, who will tell?
