In "Sound Post Office", unemployed youth Lin Yue founded a free sound post office to help ordinary people record heartfelt words and pass them to distant family and friends. After the project became popular, it encountered online doubts and counterfeit institutions riding on its heat. With the help of a group of enthusiastic neighbors and community workers, it strictly adhered to the principles of no fees and privacy protection, resolved the crisis by publishing accounts, and visited special groups to help them. A year later, the project landed in multiple places, launched the Silent Day activity, and advocated face-to-face communication. Lin Yue also found his life value from a confused unemployed person, letting silent care be heard, and kindness continues to be passed on.
