I would like to ask what is the evidence to state that origami originated in China. Paper was inveted in China, but I have my doubts there is factual evidence origami is Chinese. Where are the cranes, dogs, cats, frogs, etc. made by folding paper in China that predates those of Japan? Of so, why isn't origami present in Chinese tradition, why would it disappear all of a sudden leaving no trace of being ever created in China and practised?
