MRM (Molecular Resonance Membrane) is made by crushing rocks near the water source of Changju Village into ultrafine particles at the nano level and solidifying them with adhesives and plastics. It was developed by Dr. Jin Feng, a professor at the Chinese Academy of Sciences. The mountain village of Bama County in Guangxi Zhuang Autonomous Region, which borders Vietnam in the southernmost part of China, has long been known as the "Village of Longevity". The cause of longevity is also said to be the molecular resonance of rocks in the mountain range near the village of Longevity. ◆ Characteristics of the rocks of Choju Village ◆ 1. Molecules of water and substances are aligned and impurities are discharged 2. Generates negative ions 3. Reduced electrical conductivity * The effect is semi-permanent.
