Under the old locust tree of Yunzhou No. 3 Middle School, two generations of basketball players started a passionate inheritance - the parents hid their regrets in protective gear, and the teenagers embroidered their faith into their jerseys. From the 0:21 defeat in the first game to the reversal in the semi-finals, the old tactical boards of the "Lightning Quartet" collided with smart protective gear, and the backs of fathers training late at night finally became the light of the teenagers. When the final bell rang, the old team uniforms that had been dusted for 18 years suddenly appeared on the court: Wang Peng's burn scar wristband, Li Dashan's broken mirror pendant and the teenagers' lightning wristbands complemented each other. The two generations used their sweat to continue to write the true meaning of "basketball is not a personal battle", so that the growth rings of the old locust tree will always bloom with eternal lightning.
