Untitled Li shangyin

It was a long time ago that I met her, but since we separated, the time has become longer, the east wind is blowing and a hundred flowers are blooming.

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! .

Du Fu, the guests have arrived.

The north and south of the thatched cottage are all springs, and the flock of gulls flew in.

The old lady didn't sweep the flower path for the guests. Today, it's only for you. Chai Men hasn't opened it for you yet, but it will open it for you today.

Too far from the city, too far from good food, too thin family background, only old wine.

If you are willing to invite the old man next door to drink with you, he will drink his cup through the fence!
