hallo michael, I was at the helicatopter shop yesterday evening. sadly it was closed. Do you know opening hours?

The Silk company I did not find. its very hard to tell the taxidriver when you don't speak chinese :-)

Is there a website in china like yellow pages in europe, where you can find adresses and fonenumbers of shops?
