For the sake of family, Tongde Holographic Communication Instrument uses acoustic holography technology to act on human body. It uses the acoustic holographic communication instrument to input harmonics rich in "human-like life information" into human body, and transmits positive energy and benign information beneficial to human body through human life channels (meridians). Its mechanism is mainly embodied in the following forms: 1. Holographic dredging of human life channel network with Tongde holographic communication instrument; 2. Correct the disordered wave frequency in the human body with Tongde sound holographic communication instrument; 3. Quickly make up the positive energy consumed by human body with Tongde Sound Holographic Communication Instrument; 4. Stimulate the internal self-healing potential of human body with Tongde Sound Holographic Tongluo Instrument.
