This is a symphonic orchestral soundtrack with great cinematic picture and emotional depth. The music begins with a gentle piano solo full of nostalgia, as if opening a yellowed old photo album; then, the weeping strings (cello solo) slowly cut in, interweaving strong thoughts and memories. At about 1 minute and 15 seconds, with the addition of wind music and percussion music, the whole song ushered in an epic grand climax, sublimating personal emotions into a grand hymn to the passage of time, and finally returning to peace. It is a perfect “time” and “memory” of the auditory carrier.
