In China, there is a traditional custom that every family puts a pair of door gods posters on the door on the day of Chinese New Year. People believe that the door gods can protect their family from bad things in the new year. 

I did this illustration based on the chinese story about the two door gods. 

In ancient China, there was a mountain called Dushuo. A huge peach tree was on the mountain. Near this peach tree there was a door that all ghosts can come through to the people's world. Two talented people called Shenshu and Yulu guarded this door. Once they found out the bad ghosts who hurt people, they caught them and throw them down to the mountain to feed tigers.
