It should be "The rain is about to come and the wind will fill the building" is a poem in "Xianyang City East Tower" by Xu Hun of the Tang Dynasty.
Attached is the original poem:
"The East Tower of Xianyang City" by Xu Hun of the Tang Dynasty
As soon as I go up to the tall building, I feel sad for thousands of miles
Jianjia willow-like Tingzhou
The clouds in the stream are beginning to rise and the sun is sinking in the pavilion
The rain is about to come and the wind is filling the building
The birds are under the green Qinyuan at dusk
The cicadas chirp and the yellow leaves fall in the Han Palace
Pedestrians should not ask about the past
The flow of water from the east of the motherland to the Wei River
