What poem does "Flowers bloom and fall in spring" come from?

From "in my heart forever's Poetry Thinking of Jun", the whole poem:

It's another spring, so why should Wen Chun be in a hurry? Osmanthus shadow before the curtain falls; Adding sadness is the most annoying thing.

Looking at your shadow through the screen, the moon in front of the court is hazy; I advise you to have a drink to relieve your worries, and don't leave your lovesickness too deep.

In my heart forever's poems are a unique category of Chinese classical poems. Generally speaking, the poem that is always in my heart is about the sadness and resentment of young women and girls in the boudoir. Some of these poems were written by women themselves, and some were written by men imitating women's accents. Women themselves have the temperament of poets, with delicate feelings, easy to enter poetry, and some bitterness is even more pitiful. A happy woman may be less poetic, while a woman with delicate feelings and poor circumstances will be more poetic. When she misses her husband or lover, poetry has more meanings, more touching and more touching.

Always in my heart.

Wang Changling

A young woman in the boudoir will never be sad; Spring came dressed up and boarded Chui Building alone. Suddenly I saw the green willows, and I felt uncomfortable; Oh, I regret that I shouldn't have asked my husband to find Hou Feng.

Yuan Zhen

In the faded old palace,

Peony is red, but no one comes to see them. The ladies-in-waiting are already white-haired,

Arguing about the grand occasion of Xuanzong in Tang Dynasty.

Autumn night

Du Mu

In the autumn night, candlelight reflected the screen, and Fan slapped the fireflies with his hand. The stone steps at night are as cold as cold water, sitting and staring at the cowherd and the weaver girl.

The nearest flower

Ouyang Xiu

How deep is the yard? The willow piles up smoke, but the curtain is not heavy. Jade music carving saddle tour smelting place, the building is not high, look at Zhangtai Road.

March storm, closing at dusk, not planning to stay in spring. Tears ask flowers silently, and red flies over the swing.

Jiangnan memory

Wen tingjun

Wash and dress, lean on Wangjianglou alone, and cross Qian Fan. Twilight, my heart is broken.
