To hold a conference in China is not easy. Not surprisingly, although the venue was only announced 4 days before the actual event, the venue was canceled due to "well known" reasons. The organizers are still busy working to find another venue to make it possible for blogger flying, or taking train from across the country (some from worldwide) to gather the day after tomorrow. Exactly like the Hangzhou conference, the venue needs to be changed few times before the actual event happens. Good luck!
A technical and innovation conference was perceived in many years as a trouble maker conference, for so many years.
Well, you can’t have everything. This government made you and many other people rich in exchange for your political neutrality. There’s a saying in my country “don’t bite the hand that is feeding you” ;)
