The original sentence is "you are the concubine of a rock, and you are as tough as silk rock and as cattail."

You must be a rock, and I must be cattail and reed. Pucao and reed are soft and strong as silk, and rocks are not easy to move.

There is another sentence behind, it is a stone, so thick that it will not die for thousands of years.

My rock is square and strong, and can be stored for thousands of years, while Puwei can only be stored for a while in the morning and evening.

I wonder if you are satisfied?
