Original text:
You stand on the bridge and watch the scenery, and the people watching the scenery look at you upstairs.
The bright moon decorated your window, and you decorated other people's dreams.
Appreciate:
"You stand on the bridge and watch the scenery", but compared with the people upstairs, "you" on the bridge is the scenery in their eyes, and they "watch you upstairs"; "The bright moon decorated your window", but compared with those who dreamed of "you", "you" decorated their dreams like the bright moon outside the window.
