Spaceborne Lingering Sound

Engineer Lu Changnian is stationed at the deep space signal base station deep in the Gobi, responsible for receiving data from distant interstellar probes. There was a chaotic noise on the monitoring screen. Everyone judged it to be just the noise of cosmic radiation, but Lu Xun was the only one to decipher the hidden information. That was the secret message left in the signal to his son and the motherland, across billions of galaxies, from his father who went on a deep space mission ten years ago and lost contact. The cold instruments operate silently, and the persistence of two generations of astronauts is hidden among the vast sea of ​​stars.
