Passport Expires in less than 6 months, what can I do?

Hello, I am a Canadian Citizen and am living in China. My passport expires in 5 months but I plan to travel to Chengdu for the National day Holiday. I am currently living in Suzhou. Am I able to fly to Chengdu without any problems even if my passport expires in 5 months? I plan to stay there for about 1 week. Thanks
