::I moved it to logistics because it seems to the main crux of the dispute. You have not responded to the gunpowder weapons section for days, and new evidence (from Temple and Needham) shows that cannons were invented in China far before Europe (the 1288 cannon is only a sample; production facilities and prototypes must have been set up much longer before), so the true date is probably several decades, if not a century, in advance. The main point seems to be around the logistics section (which I have also replied to, but you have not replied). You claim Temple needs to be replaced; but so far you have not shown in any way that he has misrepresented Needham in these matters, or is wrong. Indeed, his book is fully endorsed by Needham and Pericles has already stated his views on this matter belongs to mainstream sinology (as the other science articles can show), and his book has won many awards; therefore, he is a reliable source.
