Dear, generally you can't say which is better, the infield or the stands ~
If you want to get close to them, go to the infield, at least you can flow and see your face clearly, but when they run forward, you can only look at your ass, and the queue is very tired.
If you want to see the overall effect, you should go to the platform, provided that the front and side stands are not complete, but the stands are not tired and you don't have to queue for a long time in advance.
I visited Chengdu Stadium on 1 and my seat was in the infield. Everyone stood in their seats and couldn't move freely, but my seat was in front of the main dance, and I could see my face clearly, but then I basically looked at my ass.
Nanjing Station, which is touring, is the most central stand, which is comprehensive, but can't interact.
PS: I don't know what the infield of Qingdao Station will be like, because there is no stage map in Seoul, so naturally there is no infield seat map. ...
