The staff here at the PWS has been superb. I was able to tag along to a factory visit on official design studio business. The Design studio is having a cup and saucer design made for an Australian artist. We met with the factory manager to talk shop and were then give a tour of the factory. Here is the storage rooms. I wasn't able to take photos of the rooms they work in.
When I was told that Jingdezhen makes a million pieces of ceramics a day, I wrote it off as local boasting pride. After seeing the storage room here I have become a believer.
