According to Baidu Library, Cihuazhen necklace is made of rare earth permanent magnet, and the whole necklace constitutes a circular energy circle, which is called full cycle technology. This is a patented technology. The magnetic field intensity of a single magnetic bead reaches about 4000-6000 gauss, and the magnetic force acting on the human body after being connected in a loop is about 2500-3500 gauss, so the magnetism will not be weakened.

This necklace uses artificial static magnetic field to act on human acupoints, which can repair aging and diseased red blood cells, make them healthy, and immediately restore red blood cells to negative state.
