I took out a pair of 4D glasses from Fangte Happy Garden, and I don't know what they are for.

Dude, give it up. You can't experience the dynamics of 4D itself at home, so you can only experience 3D at most. But in 3D, what you can experience at home may only be red and blue. You can hardly see and trust that your home can have two polarized projectors, and the glasses you get back from there are moving.
