A few weeks ago I was poking around among the Chinese stuff on eBay, looking for writing-related items which I buy and sell. I came upon this bronze rat which has nothing to do with writing but was irresistible. I had to have him.

I expect he features in some Chinese folktale. I've hunted around on the Internet but I didn't find anything that seemed to relate to him.

He's got some Chinese characters stamped into his bronze hide. Does anyone know what these mean?
I expect that it's a sign of second childhood when you start buying bronze rats online. For the moment, at least, there are no other signs. I haven't taken to playing with wooden blocks, nor have I lost the ability to read. I can still tie my shoelaces but for how long I don't know.
