Bruce Lee counseled: “Be water, my friend,” alternately translated as “Be like water.” The protests that engulfed Hong Kong in early summer drew inspiration from the great martial-arts star, as reported by columnist Nicolas Atkin. He detailed how Lee’s famous saying “has become a clarion call among the young protesters” and “inspired a new form of guerilla tactics … with protesters moving in unexpected waves, rolling from one spot to another.” At the same time, as Atkin reminded readers, Jackie Chan has become persona non grata among these same young people for his pro-Beijing politics, which have tarnished his reputation.
