HONG KONG/TAIPEI - For Han Dongfang, nothing that happens in China today can be worse than what he saw on June 4, 1989 in and outside Tiananmen Square - flares lighting up the dark sky, soldiers shooting people with machine guns, "crazy tanks" rumbling into the Square, people with their bodies covered in blood.

On that fateful day, the Chinese government turned its guns on its own unarmed young people who had been camped out in the Square since April to agitate for democratic reforms.
