Fairy tales can actually be truth tales. We’ve found the wicked witch, the bones of Hobbits, perhaps a few of unicorns,a real life prince of a man who fights like a white knight. It’s the verification of the dragon which is still in question.
The dragons so popular in Chinese mythology are no doubt skeletons of dinosaurs which are very common in certain parts of China. Word travels, and big bones are also found in other places.
