He went around in circles for thousands of years, seeing all the war and chaos in this world, but he could still live in Chang'an for the rest of his life.
He spent all his tender and affectionate time looking for someone.
He drinks all the misery and desolation, and sings all the peach blossoms of his life.
He watches others grow old together, and is willing to protect someone from being ignorant and carefree, to knowing the autumn leaves.
This is a bald song just for her. See how time turns the love and years accumulated for thousands of years into fine wine, squeezing all the tenderness out of the roughness.
