True, some of the pictures composing this videoclip were taken up to seven years ago, and things have improved since then, particularly in the subway, with the tones of newer lines opened now and then. See this picture, taken just a few days ago (when I arrived to this city, back in 2003, there were THREE metro lines!):
Still, both underground and up on the streets, scenes not really dissimilar to those here depicted continue to be commonplace in Beijing, particularly at certain places and certain times. A monster-city is a monster-city no matter how many real improvements you can actually apply (but, surely, these are always welcome!!).
