What does it mean to revisit the old place?

This sentence means to go back to the past and find that the environment and objects have not changed, but people have changed.

The phrase "It's human's fault to revisit the old place" was first expressed by Bai Juyi, a poet in the Tang Dynasty, in his poem Farewell to Ancient Grass, which showed the passage of time and the changes of life.

When Bai Juyi returned to his hometown of Luoyang, he wrote the poem "Revisiting the Old Place". At that time, Bai Juyi was over 60 years old. When he returned to his hometown, he found that his hometown had changed beyond recognition, and the scenery and people he used to know were gone, which made him very emotional and lost.
