Pro-democracy movement and riots in Hong Kong.

Is this a precursor to what things can be like if the Chinese government don't change? Their recalcitrant attitude towards democracy is deeply worrying. When the British left on the 1 July 1997 there was an understanding and guarantee to keep the two systems running - Communism in China and democratic Capitalism in Hong Kong. However the Chinese government has reneged on this stipulation and has rigged the election, so only government 'stooges' can stand as representatives of the people of Hong Kong. This has caused great anxiety an fear so the students have taken to the streets. They are showing great courage, but with tear gas and riot police this is a foretaste of the future? The fear of the mob in China is endemic and goes to the very top of this sclerotic and archaic system. One reason for the Cultural Revolution was to have an endless internal revolution that changed nothing and kept the authoritarian state in place. This was the paradox - a no change revolution. It must be the first one in history of its kind anywhere.
Apparently there has been a total media blackout in China of any mention of the present pro-democracy demonstrations and rioting in Hong Kong for obvious reasons. The Chinese authorities don't want the population of China to get ideas about democracy in their own country - that would be really dangerous - remember Tienanmen Square of 1989? In China its impossible to read anything about this in any publication or on the media at all. There is collective amnesia on the issue.
The sleeping giant that is Chinese democracy will one day awake and then what? When citizens have experienced democracy, despite its manifold vaults, they never vote again to be put back into their cells of incarceration. Wake up China before its too late for peaceful change.
