Yikes - I went to the Beijing Zoo in 2008, and while conditions ranged from average to awful, I did not get the sense that the visitors had a substantially different attitude toward the animals (except for the bears, whose exhibits were filled with trash). As has been stated on this site in other threads, the collection is impressive.
I was certainly aware of the deplorable conditions in some Chinese zoos, but somehow I never realized this sort of 'entertainment' was occurring in zoos like Badaling, just outside of Beijing. Just a quick google search turns up some rather unpleasant youtube videos. Shocking.
I did come across this article which is similar in content, with a different tone.
