There are about 10,000 seats on the Shanghai Grand Stage. I heard of it twice, once it was 680 and once it was 480.

I think the difference is quite big. 380 is the top floor, you should look down, while 680 is the middle floor, you can almost look up at the stage, and then the infield.

And the big screen inside is really not too big, and the color of the screen is very dark, so if you want to see clearly, it is still 680.

There seems to be some photos I took in my notebook, but I can't send them to you on the desktop now. Hey, I'll get it if necessary.
