china looking into a royal bedroom in the Forbidden City

I saw this in a palace room shut off from visitors. There were other

priceless objects here and in other rooms and other palaces in the

Forbidden City, but they were all in cases or enclosed rooms. This one

drew my attention so when I arrived home I worked to bring up the

shape and colors as best I could. If anyone knows what this is I would

like to know. It might have been in a book of palace treasures, but the

books on specific topics were in Chinese.
