I am a Canadian living in Korea. I want to travel to China. How do I get a Visa?

I have read that if you are an expat living in Korea your ARC needs to be valid for at least 6 months to get a Visa issued. My ARC expires in Sept 2012- so I don't have 6 months left. How can I apply for a Visa? There must be a way around this silly rule!

if anyone knows any information please reply!! :)
