Which department of the hotel makes the most money by experience?

As far as my hotel is concerned: KTV, of course. Our hotel integrates KTV, restaurant, teahouse and guest room, so I say KTV, with a monthly income of about 400 thousand.

Hehe, sorry. There are no stars and places in our hotel! It's just a little big. It seems to have only been open for two years, but the hardware has not been updated and the software has been updated! Very dizzy!

I don't know. Which one do you think?
