China was in chaos.
For a decade, Mao Zedong's Cultural Revolution smashed society to bits. People were sent away for brutal re-education. Others simply disappeared. For many, only one hope remained: Getting out.
"Swimming to Freedom: My Escape From China and the Cultural Revolution" is Kent Wong's memoir of those times and how desperate people tried anything — including swimming the 6 miles to Hong Kong.
"I googled the estimated number of freedom swimmers to Hong Kong during the Cultural Revolution," he writes. "According to a source in Hong Kong, it was 500,000. For sure, China will never disclose a more accurate number, even if it could."
And the number who died trying remains unknown.
Wong was born in 1948, one year before Mao's Communist Party came to power. The country was in civil war. Wong's father worked for the government of Chiang Kai-shek.
"China was a mess," Wong writes. "The violence had spread from the battlefields to every liberated village. Mao's army was shooting landlords, taking their land away and redistributing it to poor peasants."
Chiang sent many of his officials to safety in Hong Kong, which was still a British colony. He soon established a government-in-exile in Taiwan. But Wong's father had grown disgusted with Chiang's administration, which he saw as corrupt.
