     True to its name, Qingdao, the green island as its name literally suggests, is covered by abundant trees - black pines, chinars, gingkos amid the azure sky and sea.
     With green and blue as the natural backdrop, red color stands out as the human creation enhancing the charm of Qingdao, as seen from the red-roofed architecture of various European styles erected during the early 20th Century.
     With its soaring architectural triumphs, from the glorious Catholic Church to the magnificent Former German Governor's Residence and the avant-garde spectacle of the 2008 Olympic stadium for the sailing regatta, Qingdao is unique.
