On the field of Nanchuan Middle School, a familiar melody was played on the radio, mixed with the muffled sound of piling at the construction site in the distance. In the summer of 1999, the air was filled with the fragrance of gardenias, and Lin Beixing stood in the crowd, smiling like a blooming sunflower. No one knew that the boy named Zhang Wansen hid in the corner and secretly glanced at her, and the notebook in his hand was pinched out of the folds, which were densely filled with her preferences: she loved strawberry-flavored lollipops, hated ancient poems in Chinese class, and always hummed unconsciously when she ran. This crush, like a seed buried in the soil, is silent, but waiting to break through the ground one day.

Zhang Wansen's crush is like a long one-man show. He would deliberately stop at her desk for an extra three seconds while the class representative was collecting her homework; will pretend to accidentally write a word or two wrong when writing a cheering manuscript for the sports meeting, just to let her take a look at it; Even in the graduation photo, he quietly deviated half a centimeter to her. These careful thoughts, as fine as spring catkins, float in the air and are easily ignored. But the movie magnifies these details, as if asking the audience: Have you ever liked someone like this and tried your best, but didn't dare to say it?

The reunion on Fluorescent Beach is the highlight of the whole movie. The waves crash against the reef and the starlight shines on the sand, like a galactic way for this encounter. Zhang Wansen stood there, his hair ruffled by the wind, and there were a thousand words hidden in his eyes. Lin Beixing approached slowly, with a smile on his face, but there were tears in his eyes. The director used film grain to light, and the picture is like an old photo, with the heaviness of the years. It is said that this scene was filmed for three whole days, and Qu Chuxiao only slept four hours a day in order to enter the play, and he insisted on playing Zhang Wansen's forbearance and affection, which made people's hearts sour. Zhang Jianing is not far behind, she switches freely between the tiredness of the 18-year-old and the agility of the 0-year-old, as if she put Lin Beixing's soul alive in front of the audience.

There is one detail in the movie that is particularly moving. Lin Beixing traveled to 1999 years, and the teacher named her in class, and she was stunned for a moment before responding. At that moment, the chirping of cicadas outside the classroom, the chalk dust left on the blackboard, and an old postcard in the desk drawer all seemed to remind her that time was changing, but something remained forever that summer. The director didn't explain much, but it was this self-evident feeling that made people feel as if they could really turn back time. Have you ever had a moment like this? Flipping through an old book, smelling the smell of paper, and suddenly remembering someone's smiling face on an afternoon?

Lin Beixing's awakening is also moving. She found that the price of every crossing was Zhang Wansen's life. Whether it was the light of the knife in the alley, the speeding car accident, or the stormy waves under the lighthouse, he always exchanged himself for her safety. These fragments, like jigsaw puzzles, slowly put together a complete Zhang Wansen. During the filming, the director deliberately chose the old campus of Nanchuan Middle School, and the camphor trees on the side of the field are still the same as they were back then. It is said that in order to restore the atmosphere of 1999 years, the crew even reproduced the graffiti on the desk one by one, striving to make the audience return to youth in a second.

The rhythm of the movie, like a summer fan, does not turn in a hurry or slow, but it can always blow to the heart. Every scene has a chew, and every line is like an old friend's chatter, so cordial. For example, Zhang Wansen wrote in his diary: "She is not happy today, I have to think of a way." In a simple word, it makes people's noses sour. Isn't this the taste of youth? Silly, innocent as freshly plucked fruit.
