Democracy activist Xu Zhiyong defiant despite pressure
Xu Zhiyong continues to advocate rule of law and civil rights, even after being detained dozens of times and barred from teaching

Xu Zhiyong has a dream - of China becoming "a country with freedom, justice and love".
"It will be a simple and happy society with minimal hostility and divisions - and there will be innocent smiles on everybody's faces," the mild-mannered 39-year-old said this week.
But the soft-spoken law academic has had to pay a heavy price for his dream. In recent years, he has gone from being a low-profile NGO worker to - in the authorities' eyes - a major threat to social stability.
Xu has been detained dozens of times since 2009 for lobbying the government to grant education rights to migrant children in Beijing. That year, his non-profit legal aid centre Open Constitution Initiative was closed by the authorities and he was taken into custody for nearly a month.
When he was released, he was barred from resuming teaching at the Beijing University of Post and Telecommunications.
Yet none of the hardships have put him off.
