I've never seen a world leader, dictator or not, ride around in a car equipped with microphones. At least while I was watching the parade, he did not use them, and in fact was quite rigid. The past Chinese leaders all wore dark business suits and ties, but Hu Jintao had on the most exquisite Mao jacket that looked like it was made of some type of silk.
These women looked to my ignorant US-American eyes like Communist Mary Kaye sales associates. The heart-shaped balloons were a bizarre contrast to the predominant tanks, missiles, guns, and marching troops. I have no idea which organization these women are affiliated with.
I was particularly struck by this cut-off view. Much of the official government footage used the over-head shot and the cut off views -omniscient eye surveying or part for the whole - both suggesting the massive number of troops, tanks, etc. In this case as well, the goose-stepping legs clad in the sexy white go-go into battle boots resemble images of the Rockettes on stage.
