Encrypted apps and false names: new Taiwan book club takes no chances

Amid Beijing's crackdown on Hong Kong, publisher says joining clubs to discuss free speech and democracy has again become an act of resistance

In the early 1950s in Taiwan, 19-year-old Tsai Kun-lin was arrested and jailed after joining a book club. The young man spent more than a decade on Green Island, building the prison that held him as a political enemy of the authoritarian rulers who would hold Taiwan under martial law until 1987.

Decades later, a 90-year-old Tsai is living in Taiwan's thriving democracy, but says a book club has once again become an act of resistance.
