Different ages, different heart palpitations, different skies, different mottled colors, different appearances. The article begins with the protagonist Han Nuo entering the junior high school campus, and describes Han Nuo's series of growth on the road to growth. Friendship, ignorant love, tender family affection. There was laughter, there was madness, there were tears. Some are well-behaved and some are rebellious. Some are shy, some are bold, some are sweet, some are heartbreaking and scarred. Walk through one paradise and find another direction. The story of growth continues. Many years later, we met in a city that was not our hometown. The same people, different scenery, and different thoughts are confusing in the air. When we were saying goodbye, the phone calls on the bus, the slurping sounds, the words that were vague and incomprehensible through tears, placed my head in the position of those years when we were riding bicycles together, laughing and noisy. We are all older and experience different moods and lives.
