Every evening, as regular and obstreperous as a rooster, the People’s Liberation Army (PLA) soldiers sing from the barracks outside my Beijing home, a chorus of teenage troops reminding the neighborhood when it’s dinner time:

“Unity is strength, unity is strength,
The strength is iron, the strength is steel,
It’s harder than iron, stronger than steel.
Open fire at Fascism and Imperialism
And eliminate all undemocratic systems!”
