In March 2004, Bian Cheng was born in an ordinary family in Baoding, Hebei. Like all children of the same age, he spent his preschool years with his parents and education, and then entered the school to receive formal school education. "We didn't train him specially, and we didn't find his acting talent. It was not until after school that the director went to school to choose a little actor. He was lucky to be selected and his acting talent began to be brought into play. " Bian Cheng's mother said.
