In my post 'Qianmen area before the tear down 1' here, I refer to the Chinese character 'chai' '拆' which means 'to tear down'. Before an area is being demolished the buildings in that area are plastered with this character. Big parts of ancient Beijing have faced this 'big hammer' and have disappeared altogether. Several Chinese artists have criticized this in their work. Here is a work by Wang Jinsong 王劲松 called 'One hundred signs of demolition' 'chai'.

Another artist referring to this is Huang Rui 黄锐. He produced a series of works called 'Chai-na' '拆那' alluding on the big tear down of 'China'.
