following Joe's instruction, you can find the way to their house from O'hare conveniently, although I made my wrong turn. The neighborhood is safe and quiet, I met a mother and daughter led my way to their hours, but there was still some strange guy. The house is right opposite a private school and near to some restaurants. As to visit the downtown you have to walk some time to approach the red line. People in the house are very friendly especially the Chinese boy. The house is arranged place though there are about 10 people. Thank for Joe and Alex showed me some best restaurants and gave me a cap for present. joe is very energetic and easy to go. Thanks!
