The people you admire always seem out of reach
If the other party looks back, you will know that you are also on the tall building.
The unique light in oneself only shines in the eyes of the other person.
"The dangerous building is a hundred feet high, and you can pick the stars with your hands. Don't dare to speak loudly, for fear of frightening the heavens." - Li Bai's "Overnight in the Mountain Temple"
