This sentence comes from Bai Juyi's new Yuefu poem "Shang Yang Bai FA Ren". The Shang Yang white haired man refers to a maid who is vacant for forty-five spring and autumn days in the palace.

As early as the end of Xuanzong, she was elected to the palace. At that time, she was still a girl with "face like lotus breast and jade like". Who knows, "not to allow the imperial worker to meet, has been looked at by Yang Fei." since then, "jealousy is now combined with the palace of Yang" has decided her fate of "going to the empty room for a lifetime".

When she was 60 years old, she was in the age of emperor Zong Zhen Yuan, and only had the title of "the oldest in the palace". She was awarded the title of "female Shang Shu".

Bai Juyi described with compassion that she was still "fashionable" dressed up at the end of Tianbao in the last years.

The Shang Yang palace lived in the deep palace, unable to lock up, completely ignorant of the changes in the dress of the outside world, and still dressed up 45 years ago in her small world.

"Outsiders don't see and laugh. This sentence contains a lot of bitterness.

Of course, we can also see from this poem.
