The China screening took place yesterday evening, and boy was it done with big fanfare... at a large stadium and giant stage to present the movie and the special guests (Isabella Moner, Laura Haddock, Josh Duhamel, Michael Bay) to a very large crowd (probably not to see the movie though, as there looked to be way too many).

There is a video on youtube that goes for about 50 minutes, and it is done in English and Chiinese, so it's easier to watch than the recent MCON video.

The host notes that it is the "World Premiere", which makes the London "World Premiere" just an advance screening now.
(the host is very good with English and Chinese... alternating quickly between both to say everything twice)

At about 6 minutes there is a trailer that has a couple of new bits in it, and then a sit down interview with the guests.

At about 30 minutes they then have three guys brought onto stage who are "super" fans, who might have won a competition to be guests.

At about 38 minutes was a live performance of a song that looks to be this movie's theme-song, called Torches.

The guests were then waved off, and another song followed by a boy-band group... which closed out the show.

(it was raining during the event, so they got a bit wet, and needed umbrellas)
