Which hotel has good sound insulation?

Those big hotels have good sound insulation. What express hotels, seven days, Home Inn, Jinjiang Inn ... These hotels usually don't even have a personal image, so you need to swipe your card to get up. And basically they don't care about other people's business. Many people don't even know if there is anyone next door. In most cases, no one checked in and the hotel didn't have that many customers. Don't go to small hotels. Those hotels that are not chain hotels, the corridors are full of people, deliverymen and hotel employees. Don't go. If you really don't want outsiders to hear you, you can turn on the TV, but it is basically unnecessary in chain hotels.
