When was Bi's poem written?

It describes the scenery in spring. Written by Meng Haoran in Tang Dynasty.

The whole poem is as follows:

Sleeping sickness in spring unconsciously broke the morning, and the chirping of birds disturbed my sleep.

How many flowers fall after a stormy night.

I don't know when I slept soundly in the spring night, but I heard birds singing everywhere when I woke up. Remember last night when the wind was tight and the rain was heavy, I don't know how many flowers I knocked down?

The poem "Spring Dawn" seems unremarkable at first reading, but after reading it repeatedly, I feel that there is a world in the poem. Its artistic charm lies not in gorgeous rhetoric and fantastic artistic techniques, but in its charm. The style of the whole poem is as simple and natural as running water, but it is profound and unique. For thousands of years, people have read it and discussed it, as if there were inexhaustible artistic treasures in this short four-line poem. Nature without rhythm is superficial; If there are no ups and downs, it is flat. "Spring Dawn" has both beautiful charm and ups and downs of writing, so the poem is mellow and eternal. The poet wanted to express his love for spring, but he didn't say it all or fully. The windward door is half open, which makes readers ponder and guess, showing hidden twists and turns everywhere.
