Rewriting history or PREwriting history???

Many of the subway stations walls are covered in revenue producing ads (at one time the station by Tian An Men Square had huge posters featuring my daughter's then boyfriend) but a few of the original stations (the subway system has about quadrupled since preparations for the '08 Olympics began in 2000) have real artwork on there walls, each of the artful stations having their own theme. Line 2 at Jiang Guo Men? They had a beautiful mythical ancient 'sports' in tile behind trains heading North opposite modern [real] sports in tile behind trains heading south. I haven't headed south yet so I have not studied it's changes, if any, but the North bound? What was once ancient Tang Dynasty, floating through air spirit - like supernatural practitioners of kong fu with a backdrop of celestial bodies now has Chinese landers on the moon, rocket launch towers with ascending space vehicles and man-made satellites among the real celestial bodies. I do not Admire the art as much now. I will have to study the opposite wall even if I don't need to travel south. I miss the pure whimsey of their ancient 'sports.'
