What is the general rent for a medium-sized conference room that can seat 16 people?

It depends on where it is. Every place is different.

Generally, if you rent a conference room in some intermediary companies, the price is 2000-4000 yuan a day, depending on the size of the venue. If you want to rent a hotel conference room, the price is more expensive, but the hotel conference room environment is better and the function configuration is first-class, and the price is generally 20,000-30,000 yuan a day.
