Centered on Dr. X's media wall, partly concealed by newer clips, was a 
cine clip as ubiquitous in northern China as the face of Mao—Buddha's 
evil twin—had been in the previous century. Hackworth had never sat and 
watched it all the way through, but he'd glimpsed it so many times, in Pudong 
taxicabs and on walls in the Leased Territories, that he knew it by heart. 
Westerners called it Zhang at the Shang.
