This is probably a story that has nothing to do with the chaos in the world.
It comes from the story of two doctors with different medical practices in this era.
Some things will continue to fade with the passage of time, such as the cold weapons we used that year, such as that year when we flew thousands of miles into the clouds, such as that year when we rode war horses and roared to kill the enemy, such as that year when we held strong wine and became brothers under the peach blossom tree.
Some things will never change no matter how time passes.
Just like the heavenly heart of a healer that goes deep into the bone marrow and blood vessels.
It's like someone's feelings for someone that go deep into the bone marrow and blood.
