A Chinese family visiting in South Korea is going to have a problem getting back home after a four year old used his dad's passport to do some coloring.

He added facial hair to his dad's passport picture and a few more people and animals to hang out with his dad. South Korean officials say the artwork makes the document unrecognizable. They'll allow his family to go back home, but he's got some problems to deal with before he's OK'd to travel.

The father posted his son's artwork online with a plea for help.
