When Ching Cheong was a pupil at the elite St Paul's College four decades ago, he made a name for himself as a bit of a troublemaker - not for bad conduct, but for his uncompromising outspokenness.
A head prefect, he refused to read the daily Bible passage for assembly because he was an atheist.
He caused an even louder furore when he wrote an article in the school newspaper lambasting teachers for their lack of interest in students' welfare - a move that led him to being labelled 'impertinent and reckless'.
In retrospect, he said his character was later to determine his fate. He spoke in an interview ahead of today's launch of his book, My 1,000-Day Ordeal: A Spiritual Journey.
'Many people think I'm a fool, but this is my character,' he said. 'I can't turn a blind eye to things that are wrong and not say anything.'
Ching, a veteran mainland-born Hong Kong journalist well known for his dogged patriotism and idealism, believed he could help push for changes on the mainland, but he paid a heavy price for his belief.
