I was there in Beijing about ten years ago and found only a few
pieces on display, but not where you could hear them.  They were at
the Winter Palace in an open building.  What did I see?  A push-up
player and an orchestrion of sorts.

There are several musical clocks which I couldn't find, but were
supposed to be at the Forbidden City at the clock museum.  I searched
for it, but didn't find anything.
