In front of time, we can't help but sigh with emotion: how fast the days pass. In the moment when we suddenly look back, we are especially mixed. However, the longest time is the longest, and the shortest time is the shortest, because too many of our plans have not yet been completed. Years disappear, things are different, and after all, it is just a rush. Rush is the silence of time. We all know that the colorful spring scenery is pleasing to the eye, but it is not worth the four seasons. There are always some times, only after the past, will we find that it has been deeply engraved in memory!
