I was working in China in the 1999 when Clinton bombed the Chinese embassy in Belgrade.
We were told to be careful and stay in, but none of us did. Nobody that I know had any problems. The Chinese are a lot of things, but stupid is not one of them. They understood - and understand - that Americans are not responsible for the actions of the U.S. government, just like any intelligent foreigner understands that most Chinese are not responsible for the actions of their government.
