These is a map of a couple's house in Beijing.
The couple is the winner of Human Rights Award 2007 for China rewarded by Reporters Without Borders organization in France.
Hu-Jia is now been arrested into custody by the Chinese government and is been accused for "subverting state authority" and his wife, Zeng Jin-Yan and their 9 weeks old girl are now forbidden to contact anyone and are not allowed to go outside of her house, just after they got the award from RWB.
You can see where the policemen are in this map.
