As a pathologist, Feng Chi-shun would appreciate Nietzsche's adage: that which does not kill us makes us stronger. The notion perhaps informs how he escaped a hardscrabble existence in Diamond Hill, where he grew up during the 1950s and 60s.
It was a rough neighbourhood, but Feng, 63, cherishes his formative years in one of the city's most backward squatter areas at a time when manufacturing had yet to take off in Hong Kong.
'During those 10 years I grew from a boy into a man and they made me what I am today. I wouldn't trade it in for anything,' he says.
Feng chronicles his experiences in Diamond Hill: Memories of growing up in a Hong Kong squatter village. Launched this week by independent publisher Blacksmith Books, it's a rare account of life from inside the slums.
Yet Feng came from affluence, although his recollections of his early years are hazy. When his family fled Wuhan, the capital of Hubei province, before the communist takeover, they kept some of their wealth and lived in a two-storey town house on Humphreys Avenue when he was a toddler.
But it all changed after his grandfather lost a fortune speculating in gold. The family was forced to relocate and his father had to work as a teacher. Soon after, his mother died of meningitis.
