And three brothers and sisters?

There are many poems about brother and sister, such as

1. It's not easy for teenagers to leave, but it's also sad to meet again when they are old. Cao Cao's cups and plates are full of laughter, and the faint lights will last for life. Three years of self-pity for the lake and the sea, a thousand miles in the dust and sand. I want to know when the later period is, and I want to see Yan Nanzheng when I deliver the book. -Song Dynasty Wang Anshi's "Xiuchang An Jun"

When I was young, the feeling of parting was not light; Now that I am old, even meeting each other makes me feel sad. Prepare some dining tables at will, so as to chat while eating; The lights were dim, and we poured out our thoughts and thoughts to each other until late at night. I'm feeling that after three years, I'm leaving you to go to Liao country thousands of miles away and travel to sand. If you want to ask me when we will meet, how can I be sure? When you see geese flying south, there will be a safe letter from me

2, it should be * * * three-night reward, jade building or water curtain. -"Farewell to my sister Song Huayang on a moonlit night" Li Shangyin in the Tang Dynasty

I hope I can enjoy the moon with my sister Song Huayang. I guess the crystal curtain on the jade pagoda is as transparent and bright as before.

3. I feel that I miss my sister-in-law very much and I am worried about my life. Wan Li, after many years, was lonely all night. -"Send the younger brothers and sisters in addition to the night" Tang Bai Juyi

After being separated from my sister-in-law for a long time thousands of miles away, I can't help thinking about them when I am alone in front of a lonely lamp at night. These two sentences are like a lonely lamp sitting at night, very vivid.
