Those of you who are familiar with my blog will know that I live in Hong Kong, and my last post of 2012 is a discussion of the ancient Chinese custom of painting "door gods" on the main entrances of buildings to prevent the entry of evil spirits. The models for these guards were two Tang Dynasty generals, and I've included three examples from public buildings [two ancestral halls and a temple] close to my house in order to compare how these are portrayed.
