Don't be nostalgic for the scenery you missed, and don't entangle the passers-by who left. Only by bravely saying goodbye to the wrong one can you meet the right one as soon as possible.
In everyone's heart, there will be a beautiful distant place. If there is a bright light in your heart, you will get a distant and close feeling, which will make your life more fulfilling and interesting, and make your dreams flutter and ripple.
