"Rivers flow into the sea, and thousands of miles are made of fine copper."
"It's hard to meet like water, the impermanence of this world"
There is an ancient room with thousands of documents recorded,
Deep in the room is a small box that looks shabby but is exquisitely carved.
No one ever pays attention to it, let alone drives it
Permeated with a strong mysterious atmosphere,
No one knows that there is a copy in the box...
