Lin Xingxi, who has a background in neuroscience, unexpectedly became the guardian of cute baby Wen Yan. She discovered that the gentle sound of laughter could be wonderfully soothing. With the help of EEG equipment, Lin Xingxi captured Wen Yan's unique "warm rhythm" of brain waves and developed an "emotion regulation headset" based on this, bringing hope to patients with depression. However, when the hidden dangers of over-reliance on "warm rhythm" began to emerge, Lin Xingxi resolutely turned to the path of integrating natural growth and technological intervention. This is a joint growth of love and science, using the warmest rhythm to compose a double movement that heals the soul and cultivates the future. Technology has degrees and growth has warmth. Compose a song with the warmth of technology that brings body temperature.
