The Most Comprehensive Demonstration on Quadrangle House of Beijing 

Thank you so much Yanyan, I have always admired the quadrangle houses of Beijing, it is great to get a better look at them

Many thanks for showing a candid view of the current quadrangle houses in Beijing. It's sad to see the sorry state of the few that remain. That's the fate of the historical artefacts in a poor country. It's really too bad that China became prosperous only after these had been neglected for decades.
