ABSTRACT
In Xinjian there was a scholar by the name of Zhang Yacheng who from the time he was a child loved to make his own toys and costumes. His attic was filled with helmets, beautiful dresses, and a variety of precious bits of shiny patterned paper. He would play with his treasures by himself in the attic, and as an adult he kept his toys. But their existence remained a secret from his family.
