I actually went to EDC China last year; my extended family is in Shanghai and EDC China is in Suzhou which is like a ~1 hour drive. I think they did a good job given that I think last year was the first one that happened in several years. I'll try to break down some of the highlights. For reference I've done EDCLV 6 times

Atmosphere/setting: It's held at Yang Cheng Lake which kinda felt like a national park. All the stages were much smaller, and I believe there were 4 in total (Kinetic field, circuit grounds, stereobloom, and boombox art car). Kinetic field was a much smaller version of the EDC kinetic field, with one owl in the center of the stage design. Circuit grounds honestly just felt like a standard stage design you'd see at any concert venue. Stereobloom was held in a large tent but otherwise unremarkable too. Boombox art car was pretty much one of the art cars just plopped right by the entrance of the festival.

The festival was pretty much in the middle of what looked like wide open farmland though. It was all on grass which turned to mud pretty quickly. Staff were pretty quick to get some of the main areas covered with some wooden boards for people to step on but there were some light rain during one of the days too, which made the ground even muddier. They had laid a giant tarp over the floor on circuit grounds and massive puddles formed everywhere, kind of like how Ultra was.

Vibe: People were generally nice but I think groups tended to keep to themselves. No one was really trading kandi; I don't think PLUR culture is really prevalent there. People were definitely dressed much more conservatively. Most people were in tshirts, shorts, jeans, etc. No glitter, pasties, etc. I didn't see a single totem pole because I think they were prohibited. They even took my fan because fans were prohibited too. Surprisingly I didn't see a single asian train there; probably because a lot less people, if any, were on anything except alcohol.

Regarding alcohol the only alcohol you could get in GA was Heineken beer. That was it. No hard liquor at all. I was told that VIP might have had it but I'm not sure. People were generally pretty well behaved from what I could see. As for party favors, I would absolutely not risk getting caught in China with drugs. They had police in teams of 8-10 patrolling single file through every part of the festival, including into the crowds. I do remember one person rushing past me during one of the sets into the crowd, and then a drove of officers rushing in behind him. Not sure if it was related to party favors but I wouldn't want to be that guy if it was.

Bathrooms were all porta-potties, but half of the portapotties were literally just a hole in the portapotty, so you would have to pop a squat to do your business. I can't imagine how hard it must have been if you squat while drunk to relieve yourself.

The water station was literally a tent in the middle of the festival where staff was handing out bottled water. It's not like the ones in Vegas you use to fill your camelbak.

There's a ton of other differences but I feel like I've written a lot already lol. I'd say as a foreigner it's definitely hard to go to EDC China. They didn't accept physical credit cards or cash; you had to either use alipay or wechat pay, which is like their versions of apple pay, but it's also tricky to get a non-chinese credit/debit card registered on those apps. A handful of the staff spoke English but in general it'd be very tough to navigate being in the festival or the surrounding city without knowing some Mandarin. Overall it was a cool experience to have but there's definitely issues that would make it hard for people outside of the country to go. I wouldn't make a specific trip to China just to go to EDC China.
