"Choose a city to die, and meet a person with white hair". I don't know where to see this sentence, I can't help but feel moved. I think that in this life, there will always be a person who will hold your hand, integrate love into life, dedicate all his life to be gentle, stay with you to paint white hair, and accompany you to see the long flow of water. How many fireworks in the world are quietly dense in the thin and fragmented time; How many vicissitudes and frustrations, in the years of hand in hand, Ren's face slowly grows old in the dull day after day, although the flowers fall, the wind lives in the dust; The water flows and the clouds fade away, but what remains unchanged is each other's old smiles.
