Mr. Cai Guancheng was a 73 year-old retired worker from the First Construction Company of Beian City, Heilongjiang Province. He used to suffer from various illnesses until after practicing Falun Dafa in 1996. Since the persecution began, he was repeatedly harassed and threatened by the local police. As he was afraid of being persecuted, he was forced to give up practicing Falun Dafa. Soon, his past illnesses recurred and he even contracted cancer. With the help of other Falun Dafa practitioners, he began to practice Falun Dafa again. His body, however, was extremely weak due to the persecution and he died in the hospital on February 24, 2003.
