On the 19th November 2010 the CCRCGP at Bifengxia hold a double ceremony to show the 16 Giant Panda cubs born there in 2010 and the re-opening of old Leopard Mountain which is now to be known as the panda returnees paradise park. The new park contains a set of 3 pens containing 7 villas which can accommodate more than 10 sub-adults. This is where Zhen Zhen and Sulin were moved to as mentioned in a previous post. When I was there, there was only 2 pens, so I'm assuming that another one has been built. I will try to get some more information about this.
