Xuang lian bi is literally translated as Double Connection Bi. It is a shape orginating from the Hongshan Culture about BC.4000–3000 BC.
But inspite of the story which gave me a good laugh, I still bought the piece though not at Hongshan price. After all its quite nicely made, the jade is an attractive pale green, and this delicate piece appeals to me as my normal preference is for small over big. I am also optimistic that it may be made by a Ming miniaturist after my own heart. A final advantage is that I can wear it as a pendant strung up with my personally hand knotted cord.
