Take the time to look up.
Guard camel (dates to Ming Dynasty). Check out the beautiful detail of the door.
If you are ever on Oahu, I highly recommend taking the tour of Shangri La. Up to this point, the Lyon Arboretum has been my favorite place on Oahu, but I enjoyed Shangri La so much that they are now tied for #1. I would happily go back again to absorb all of that gorgeous artwork!
