As a group of old birds who have surfaced on the web, we have always had a special love for the photos. As the saying goes, a picture is worth a thousand words. Often staring at the pictures fraught with vicissitudes and yellowing scents, we deeply feel the fragile heartstrings are trembling again and again. We lament, we also praise. We want to be able to recall that moment and enjoy the moment of history. Wish you a wonderful day.
