Beijing have appeared very late, they only declared they intended to bid at the start of this year(see earlier post). This makes it quite hard for people to have had a chance for us to ask questions, and for them to come up with answers for some of these questions. It makes them seem a little disorganised. When Helsinki in 2015 appeared late, they still did it a full year before the Site selection vote.
I hope that the Bid team will not be discouraged by some of the response that some fans have had, and consider coming back at a later stage.
A Chinese Worldcon would be very different, and I would love to attend one. The current bid committee have impressive facilities.
More information on the bids, along there formally submitted bid documents are available:
So it is worth having a look at both, and if you are voting make an informed vote.
