In December 24th, 1992, Zheng Fengchen died naturally in Xianghe Country, Hebei Province, China. However, her temperature didn’t come down after her heart stopped beating for 24 hours. Even a week later, her body remained as soft as alive, and the veins in her temple still clear to see, being full of elasticity. Stranger thing is that there is blood flowing through the back of her hands. After 3 years under natural conditions, the body of old Lady Zhou Fengchen had been evolved info "Diamond Glazed Body".
According to modern science, modern chemistry basically classified matter into organic matter and inorganic matter. The biggest difference between them is that the organic matter will decay gradually under natural conditions provided that the organic lost its life, but the inorganic matter will not. To prevent the organic matter from rotting, modern people usually dip the body in various preservative liquid.
The un-rotten body of the old lady, Mrs. Zhou Fengchen, is a phenomenon which can not be explained by modern science. And it has aroused great interest from specialists in various walks of life in the society. They have many different presumptions on cause of the formation of this mortal body like Zhou Fengchen’s living condition, religious belief, or preservative environment. However, there is no a convincible explaining on it. Many people are waiting for the answer of this mystery.
