Leaving the airport?

My girlfriend and I have a flight from Shanghai to Malaysia. We have a lay over at the airport in Shanghai for 10 hours. We are wondering if we can leave the airport and get lunch somewhere in Shanghai. I am a Canadian citizen living in South Korea and she is Kenyan living in South Korea. I have over six months on my Alien card and E2visa for South Korea. She has 3 months on a D2visa remaining.


Thanks,
