I can't. According to the information of Beijing-Tianjin-Hebei online network, Fuyong Cave in Lingshou can't cure diseases. Fuyong point in Lingshou is a "natural nursing science" advocated by Chairman Zhao Shuxiang all his life. It does not cure diseases, but it has the magical effect of nourishing and eliminating diseases. Adopting high negative oxygen ions+bath geomagnetism+original ecological health exercises+treatment of tea, diet therapy, sleep therapy, sweat therapy and sunshine therapy is a kind of green natural therapy.
