Wow, what a trip! Since you're already travelling such a long distance, you have so many options. You can arch up north towards Mongolia (and the Great Wall), or you can sweep down south towards the coast.(If it was me, I'd be sure to go through India and make a stop in Agra to visit the Taj Mahal.) I think it also depends on what time of year you would be travelling; I wouldn't head towards Mongolia in the wintertime, it might get chilly.
And don't forget about the big Tibetan plateau; I'm not sure how you want to approach that. Whichever direction you choose, I think you should head towards Bandar Abbas or possibly Bandar-e Lengeh, where I imagine you can take a ferry across that little strait to the peninsula that holds Dubai. The distance from Shanghi is 3998 mi.
(6434 km), so the length of time the trip will take depends a lot on how much travelling you want to do each day. I've been wanting to go to Dubai since learning about the amazing architecture boom going on over there. And what an added bonus to make the journey on your bike.
There's a little bit of jealousy on my end over here, I'll admit it. Good luck to you!
If you can get the permits, I would travel through west into Kazakhstan and into Russia, come down through Azerbaijan, down through Iran, across a small strip of Iraq and into Kuwait. From there, you can take a ferry. That way, you avoid, Burma and Pakistan.
Another way would be to travel west through Azerbaijan into Georgia and enter Turkey and then travel south through Iraq. But the southern Iraq trip would probably be safer.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
