The wound has healed. Tell me about it.

This sentence expresses a metaphor, which means that even if the wound heals, the scar will still remain. It can be used to describe the process of psychological and emotional recovery after a person experiences trauma or difficulties.

The specific explanation is as follows:

"No matter how deep you row, the wound will heal": It means that no matter how serious and deep the wound is, time and healing process can help the wound heal gradually.

"No matter how fast it heals, it will leave scars": It is pointed out that even if the wound is completely healed, the scars left are still inevitable. Scars here can symbolize the traces of pain, memory or experience, which may affect a person's thinking, mood or behavior to some extent.

This sentence means that although we can gradually recover from the trauma, the pain or difficulties we have experienced may leave some indelible marks. It reminds us to accept our own experience and understand that even if the wound heals, these traces may still exist in our hearts. However, this does not mean that we can't continue to grow and advance, but learn to accept and live with these scars.
