Immortal at the river by Yang Shen (1488–1559) is the poem seen in calligraphy on the photo. It talks about the transience of all human things and the permanence of nature. "On and on the Great River rolls, bending east away. Of proud and gallant heroes its white-tops leave no trace. As right and wrong, pride and fall turn all at once unreal. Yet ever the green hills stay. To blaze in the west-waning day.“ (…) In my series, I examine representative public spaces of prevailing political systems in China, namely the Ming dynasty of the 15th century and the Peoples Republic of China of the 20th century. Those spaces are idealised, architecturally manifested ideal concepts of harmony as an imposed world and social order. The creation of a new world order is propagated on the last photo. (Win a new victory in building a moderately prosperous society in an all-round way, and create a new situation for socialism with Chinese characteristics!) The social enactment of harmony is reflected in the relation between architecture and nature, as well as free spaces and people, and offers people a stage for self-presentation in order to enter into an idealised relationship with the built space.
