When I went up to Tacheng village to attend a Nature God Ritual, HeXiudong's cousin YanJiahua, the paper-making Dongba, asked me to make a drawing of Langyo for him. He gave me two pieces of his homemade Dongba paper to work with, and photocopies of original linework by Mu Cheng to base the drawing on.
I started a separate drawing of Xiuqu (Dapeng Bird, aka Garuda) on the smaller piece.
