Can Shanghai Disneyland bring its own food?

I decided to give you an accurate answer with practical experiments. I packed an unfinished hamburger for hotel breakfast, a bag of grapes bought in the supermarket (the kind sealed with plastic wrap), 2 bottles of unopened mineral water, an apple, 3 peaches, a bag of ham sausage, 5 spicy sausages and a bag of raccoon noodles. Only hamburgers were singled out for processing during the security check, and the others were released at a glance. Therefore, fruits can definitely be brought, and it doesn't matter if mineral water can't be opened, but cooked food is absolutely forbidden. In addition, you don't need to bring a lot of water, it's all direct drinking water.
