Chinese house

This card shows the Zhongyun residential quarters .It was sent by Deng Jiang Ke of China. It looks like an ad card to me, but I am not sure .

Nice stamp. The one on the right is a prepaid stamp. The cancellation mark is quite interesting as it is in Mandarin, unfortunately I don't read Mandarin ,so I don't have clue where it was canceled. Anyway, thanks Jiang Ke
