How about the Dongsheng Experience Hall challenge for 3 days?

The 3-day challenge of the Urban Experience Museum is a routine and a stunt for the merchant, because he needs you to pay the deposit of 5, yuan. No matter whether it is successful or not, the deposit will not be refunded in the end, and it will give you many restrictions. With these restrictions, no one can complete this challenge, so it is a routine.

The challenge of Dongsheng Experience Hall for 3 days requires customers not to bring any electronic products, any accompanying things, to stay in a confined room, to turn on the lights 24 hours a day, and not to take a shower all the time.
