Scheele's Gate
If you see a light green door at the end of the road, calmly walk back immediately and escape to a crowded area before the surrounding doors have turned light green together. Don't panic, be calm; if it knows you're panicking, there's no escape. That's all I can tell you - no one knows where exactly the green doors lead to. I was shopping with a friend one day; he did not pay attention and accidentally went through one of the doors. His phone never answered after that, and we never saw him again.Announcement Regarding Internal Planning Adjustments at Longgui Library's Main Building (2018.4.7)If it's a door near you that turns light green, leave that place immediately; if it's a door at the end of a hallway that turns light green, turn around immediately and leave the building you're in. DO. NOT. COME. BACK.
