Liu Xiaobo's "June Fourth Elegies"

Before his arrest in 2009, Nobel Peace Prize laureate Liu Xiaobo would write a poem every year to commemorate the 1989 Tiananmen crackdown.

The poems have been translated into English by Jeffrey Yang and published in the compilation, "June Fourth Elegies."

I talked to Yang about Liu Xiaobo's poetry, and the power of poetry to remember an event that has been publicly erased in China.
