The difference between hotel service elevator and public elevator

What is the difference between a public elevator and a private elevator? Generally, private elevators are domestic elevators and can only be used by family members. Outsiders can't use it, which means it can't be used commercially. For example, the second floor is a shop. If the elevator is installed, the renter can't use it. Not if you use it. If the quality supervision bureau finds out, it will be fined. Private elevators are generally below 0.4m/s, and the national standard is not more than 0.4m/s..
