In the vicissitudes of life, an old man with white hair and white beard walks in the afterglow of the sunset, looking at the busy traffic and the colorful flowers on the roadside. There are candied fruits and dried fruit vendors selling them. The red plums are wrapped in a layer of white frost, which is very much like the woman's bright red lips. She was also standing there that day, wearing a white gauze skirt, taking a plum and putting it in her mouth. The sweetness and sourness seemed to melt into her heart, and then she smiled, revealing a deep dimple that also made him drunk in his heart. He thought so, and only wanted it to be engraved in his eyes.
